Peterson: A joint review of your proposed circuit board production activities has been conducteC by the City Building Safety Division, Fire Prevention Department and the Department of Environrnental Affairs. The following requirements are deemed applicable to the safe storage, use and disposal of the chemicals utilized in your electroplating and etching processes. STORAGE OF CHET,IICALS The Uniforn Fire Code requires the following provisions relative to the storage of potentialLy hazardous chemicals : Oxidizing materials shal1 be stored in coo1, ventilated, dry location and separated from organic materials. BuIk oxidizing materials shall not be stored on or against combustible surfaces. Corrosive liquids shal1 be stored in cool, ventilated, dry location and protected against physicat damage and water, separate from oxidizing and combustible materials. Inside storage of chemicals shall be limited to quantities needed for process opera- tion. Bulk storage is not allowed unless Code provisions for bulk or Hi-Pi1e storage are met. 4. Chemicals shall not be stored in any way that would block an exit path or exit door. 5. If the storage of oxidizing and comosive naterials cannot be separated far enough . to satisfy all Code requirements, partition walls sha11 be required for separation. Coordinate the above listed requirements with Mike Hudman of the City Fire Marshals office. Please'direct all inquiries regarding chemcial storage to the Springfield Fire Prevention Department at 726-3737 . USE OF CHEMICALS A product-conveying ventilation system, designed in compliance with Chapter 11 of the Mechanical Specialty Code and Mechanical Fire and Life Safety Code, shal1 be provided above the polypropolene vats utilized in the electroplating and etching process. The hood and duct system shall be protected with suitable corrosion-resistant material as L 225 North 5th Street o Springfield, Oregong7477 . 503/726-3753, 503/726-3737 Ivlr. Bob Peterson Circuit Board Production Requirements January 3, 1984 Page 2. ) recluired for Class 5 systems conveying corrosives, such as acid vapors. Coordi- nate ventilation requirements with the City Mechanical Inspector. Due to the potential for back siphonage or cross connections which could contami- nate the potable water system, a reduced-pressure backflow prevention device will be required on the water service to the.:chemical use area of the building. Coor- dinate water service protection requirements with Tim Hanley of the Rainbow Water District and with the City Plumbing Inspector. A separate letter will be sent to you from the Rainbow Water District regarding water service protection. The area where hazardous chemicals are handled, transfered or used shal1 be pro- vided with an approved floor and wal1 surface which is not adversely affected by the chemicals being used. This area shall be sloped, curbed or otherwise designed in a manner capable of safely containing any accidential spillage or leakage which could occur until "c1ean-up" operations could be performed. Care shal1 be taken in the design and construction of the hazardous chemical con- tainment area to assure that the City wastewater system is protected from the pos- sibility of accidential discharge of prohibited chemicals into the systen. A sep- arate letter will be sent to you from the Department of Environnental Affairs re- garding prohibited contaminants of the wastewater system. Alteration or extension of electrical circuitry requires an electrical permit and inspections. State of 0regon Administrative Rules require that all electrical wiring on properties for rent, sale or lease be performed by an 0regon licensed electrical contractor.

No other cleaner otfers the economy and capacity ol alkaline, hot soak, cleaning. The circuit board industry, since its incep- tion, has depended on alkaline cleaning, and Chemline's Adclean 6A fulfills this requirement. A 10 ml sample is removed from the production bath and transferred to a 250 or 500 ml flask. Dilute with 100 ml deionized water, add 3 or 4 drops phenoph- thalein indicator and titrate to a clear endpoint with 0.1 N acid. A new 9:'l bath will titrate to 21-22 ml. Use the chart below to maintain a 9;1 dilution strength. APPLICATION INFORMATION Adclean 6A is designed to remove light soils, finger- prints and tarnish lrom copper laminate. lt can be used prior to electroless copper or plating.Titre in ml Addition in ml per gallon of productlon bath 60 95 131 166 203 237 275 BATH MAKE-UP 'I part Adclean 64 9 parts water (Dl preferred) 18.0 16.0 14.0 12.O 10.0 8.0 6.0OPERATING INSTRUCTIONS Adclean 64 can be held in steel, stainless steel, plastic or glass. lmmerse parts for 3 to 5 minutes followed by vigorous rinsing.

BATH CONTROL & MAINTENANCE: PEROXY ETCH 63 solutions can be conlrolled and maintained for optimum performance by several methods: work load, titration, specif ic gravity and certain operating characteristics. Titration and specific gravity will generally provide the most reliable method of bath control and mainlenance. Balh Conlrol - PEROXY ETCH 63 by titration l. Procedure: 1. Pipette a 1.0 ml sample of bath into a 500 ml Erlenmeyer f lask containing 200-250 mls distilled or Dl water. 2. Add 3 mls sulluric acid and mix. 3. Add 5-6 drops Ferroin indicator. 4. Titrate with standard 0.'l N ceric ammonium sulfate solution f rom an orange-red to a pale blue end point. 5. Calculations: Divide the mls of ceric sulfate solution used by 16.5 to obtain percent PEROXY ETCH 63 in bath. Example: ceric sulf ate solution used = 12.7 mls. Percent PEROXY ETCH 63 in bath = 12.7 + 16.5 =77.0o/o. Note: Fresh bath contains 6.5% PEROXY ETCH by volume. lt is recommended that the bath be kept at 65 to 100% of the original strength at all times. ll. Reagents .l . Ferroin lndicator: Dissolve 1.285 gms 1,10 -Phenanthroline and 0.695 gms f errous sulfate heptahydrate in 100 mls distilled or Dl waler. 2. 0.1N Ceric Sulfate solution: Dissolve 63.25 gms ceric ammonium sulfate dihydrate in 600 mls distilled or Dl water containing 30 mls sulfuric acid. Filter if turbid. Dilute to exactly 1 liter in a volumetric f lask. Bath Control: Sulluric Acid Content by Titration. 1. Pipette 5 mls bath sample into a 250 ml beaker or Erlenmeyer Ilask containing 75-100 mls Dl water. 2. Add 2-3 drops methyl orange indicator. 3. Titrate with 1N NaOH solution to a yellow end point. When copper sulfate is present in solu- tion the end point will be yellow-green. Calculations: Sulfuric acid, o/o by volume (66'Be) - mls NaOH used x .58. Bath Control: Specilic Gravity Specific gravity establishes two important elements of control sulfuric acid and copper sulfate content. Graph number 4 provides essen-tial information for controlling solutions of PEROXY ETCH 63 by specif ic gravity. Bath Control: Square Footage Work load is a supplemenlal method of con- trolling solutions ol PEROXY ETCH 63. lt shoutd be used as a complete substitute for titration or specific gravity. Square footage processed through the bath should be recorded and replenishment made on lhe basis of one gallon of PEROXY ETCH 63 for each 2400 and 2800 square feel of laminate processed. Sulfuric acid should be added as a ratio of the pEROXy ETCH 63. For each gallon of PEROXY ETCH 63, add .7 gallons of sulfuric acid. COPPER RECLAMATION: When the copper sulfate content of the bath reaches approximately 32 ounces per gallon as determined f rom the specif ic gravity chart, transfer the solution to a holding tank. By titra- tion, determine the sulf uric acid content. Add the necessary amount oi sulfuric acid to bring the bath to |1oh by volume. Allow the bath to cool to room temperature. The copper sulfate will crystalize and precipitate. The bath can then be decanted back into the processing tank. TitrateIor PEROXY ETCH 63, make the necessary acljustments and the bath is then ready for re-use. OPERATTONAL PROCEDU RES: I Through Hole Plating When used in the prescribed manner PEROXY ETCH 63 will provide smut free uniformly etched surfaces which are highly receptive to electroless copper deposition. The number of processing steps is also reduced. The following is recommended: 1. Preclean in Adclean 6A 2. Dl or tap water rinse 3. PEROXY ETCH 63 4. Dl or tap water rinse 5. Hydrochloric Acid 6. Adion Catalyst 550 7. Dl rinse 8. Accelerator AC3 9. Dl rinse 10. Copperdep 400,420 or 707 11. Dl rinse ll Multi Layer Applicaton PEROXY ETCH 63 offers several major benef its in the processing of multi layer circuit boards. Unlike ammonium persulfate, PEROXY ETCH 63 exhibits far less activity on oxide coatings on inner layers. PEROXY ETCH 63 plus a salted catalyst system such as Adion Catalyst 550 will contribute signif icantly toward the elimination of "haloing". PEROXY ETCH 63 will have no adverse effect on phenolic or epoxy laminates nor will the metallic stabilizers within the f ibre glass itself degrade PEROXY ETCH solutions. The same cycle f or THP boards applies to multi layer processing. lll Prior to Resist Applicaton The use ol PEROXY ETCH 63 prior to silk screening or dry film larnination will increase the physical bond between the copper surface and resist resulting in better plating definition. A suitable process is as follows: 1. Alkaline preclean with Adclean 64 2. Water rinse 3. Acid preclean with Acid Cleaner #5 4. Water rinse 5. PEROXY ETCH 63 6. Water rinse 7. Apply resisl lV Prior to Pattern or Tab Plating The oxidizing qualities of PEROXY ETCH 63 assure clean plateable surfaces. Any organic contaminants from cleaners or rinses will be oxidized by PEROXY ETCH 63. The same applies to residual solder prior to tab plating. Trace amounts of solder or organic matter will be removed by PEBOXY ETCH 63. The procedure recommended in thispreceeding seclion can be utilized for this application. 31 rso"r l{r'r r 30'F 120'F I lo"F l6'r 90"f 80't 10'f Etch Rate As A Factor Of Temperature At A Constant Time Of One Minute I I I 23 50 ts tm t25 MICRO INCHES PER SOUARE INCH 150 Etch Rate As A Factor Of Time At A Constant Temperature Of 110"F I I Etch Rates With Varying Amounts Of Peroxy Etch 63 At One Minute And 110'F 100 95 90 -85 o i! 80 oEu75A ;t ?0 65 60 5S .]o ffr to 50 llo ltt tta 122 126 MICRO INCHES PER SOUANE INCH Specific Gravity Chart For Determining Copper Sullate Content 42 oU F) =E il lb UF L J JI o U c20oo o zt6oJ o .,tU UOxz fo I10 lrtt 150 o // o\ MICRO INCHES PER SOUARE INCH t00 SPECIFIC GRAVITY AT 1IO"F t30 t34 I o -"'l I ACCELERATOR AC3 TECHNICAL DATA SHEETMLINE There's always a Chemline solution DESCRIPTION: Accelerator AC3 is a supplemental bath, following catalyst, offering the following benefits: 't .

REV. 9-81 SALT CATALYST PROCESS PREDIP 555 AND PREDIP 555 SALT E INDUSTRIES CATALYST MAKE.UP TECHNICAL DATA SHEET There's always a Chemline solution The Predip 555 Salt Catalyst process is comprised of two parts and is designed to provide a highly active catalytic surface on suitable subtrates in order to pro- mote subsequent electroless copper deposition. The f irst part of the syslem is the Predlp 555 solution which functions both as a conditioner for proper acceptance of the catalyst and as a replenishing drag-in solution for maintenance of the catalyst. The second part of the system is the Predlp 555 Salt Catalyst solution com- prised of the Predip 555 and the palladium chloride Catalyst 550 concentrate. Used for the make-up of both the Predip 555 solution and the Predip 555 Salt Catalyst solution, the Predip 555 salt has special additives which inhibit attack on copper foil and prevent displacement reactions with flame retardents which can cause activating and plating prob' tems turther down the P-T-H line. Attack on black oxide inner layers is also eliminated. MATERIALS REQUIRED l. PrediP 555 solutlon: The Predip 555 Salt is supplied in 100 # containers and is used at a concentration ol 2#,4 oz.lgal.(270 g/l). No other additives, except deionlzed water, are required' The Predip 555 solution is used immediately preceding the Predip 555 Salt CatalYst tank. ll. Predip 555 Salt Calalyst: The Predip 555 powder is used in combination with Catalyst 550 concentrate and deionized water to prepare the working Predip 555 Salt Catalyst.

Take all precautions as in handling hydrochloric acid. Wear acid resistant goggles, gloves, and clothing when handling. Avoid contact with eyes and skin. ln case of conlact, f lush exposed areas at least 15 minutes with water and, if necessary, consult a Physician. WASTE DISPOSAL The Predip 555 and Predip 555 Salt Catalyst solutions should be adiusted with sodium hydroxide to a pH of 7 + 1 @ 75'F. They should be filtered and discarded. The tiltered sludge should be treated as metallic waste. Local regulations should be observed when discarding effluent liquid. WARRANTY (' ELEGTROTESS GOPPER 7Ol8 IN E ES Copper Both TECHNICAL DATA SHEET There's always a Chemline solution Bath Description CHEMLINE'S ELECTROLESS COPPER 708 Copper Eath is designed to deposit a bright, dense. coherent copper film on conductive and catalyzed non-conductive surfaces. ELECTROLESS COPPER 708 Copper Bath has long life and excellent stability and is very easily controlled over a broad operating range. Bath Makeup The bath is made up from two concentrates as follows Deionized Water 80% by volume ELECTROLESS COPPER 708 A 10% by volume ELECTROLESS COPPER 708 B 109/, by volume The components should be added slowly and mixed tho- roughly in the order given. Bath Operation A. Equipment 1. Tank - rigid PVC, CPVC, Polypropylene or 2. Agitation gl ass. - constant solution aeration with clean d , oil-f ree air is necessary to ma nta tn an on which will gently give uniform distri- bution of solution through the holes is also recommended. - if used, it should be a water-jacketed tank or a non-metallic heat exchanger. - they should be 316 stainless steel or a suitable plastic. They should be free rinsing and distribute the work load evenly throughout the bath. 3. Loading Up to 3.0 square feet of srJrface area per gallon of bath solution. 4. Filtration Periodic filtering through a 10 micron filter to' remove particles... dust. and other contaminants is recommended. 5. Plating Rate The bath will deposit a copper film thickness of about 20 microinches at 75o F. in 15 minutes. Plating rate will drop off sharply after 20 minutes immersiorr time. Bath Maintenance The bath may be replenished based upon copper concentra- tion. All replenishments made should be in the following order: Add Concentrate A slowly, mixing well Add Concentrate B slowly, mixing well The necessary analysis procedures required by each particu- lar installation will be supplied by CHEMLINE. Laboratory equipment for each analysis is generally supplied by the user or may be purchased from CHEMLINE. Referring to the copper analysis sheet, determine the cop- per concentration of the bath. Using Table I or Table ll, obtain the proper addition to be made. TABLE I Additions for every 10 gallons of ELECTBOLESS COPPER 708 4 Heater Racks B. Operating Conditions 1.

For overnight or weekend storage, it is advisable to have the bath at or below 7O% of the original makeup concentration. 2. Air agitation of the solution should continue. Restarting the bath - 1. A copper analysis should be performed' 2. Additions of Premixes A & B should be made based upon the copper analysis according to the normal ad- dition schedule. (See Table I or Table ll.) Tank Conditioning 1. lt should be a regular practice to periodically leach the electroless copper tanks. As the result of abrasive contact of catalyzed circuit boards with the interior tank walls, copper will begin depositing in these sen' sitized areas and eventually result in excessive copper deposits causing bath instability. Once aweek orafter an extended period of dormancy, leach the electroless copper tank with Peroxy Etch 63 or ammonium persulfate. Follow with a thorough rvater rinse. lf persulfate is used for leaching, a 10% sulfuric rinse is recommended followed again by a thorough water ri nse. 2. Any time that the bath is transferred. either for stor- age or tank cleaning, the bath should be filtered. A filtering device and filter (10 micron pore size) with low absorption properties such as a polypropylene filter and a non metallic filter pump are helpful to remove small catalytic particles that abrade off the work. Waste Treatment Basically, an electroless copper bath contains two compo- nents which must be waste treated before disposal. These arethecoppersaltandthecausticsoda,Thecoppersaltis most effectively and economically removed by precipita- ting metallic copper from the solution. The remaining . solution is then neutralized with acid and is disposed of. . , For specific instructions see the separate .sheet entitled " .,, "Waste Treatmgnt of Eleitroless CoppelEatlii".:' r.,, .. : '' j i\. .'':,' Safe Handling Electrolesss 708 Premi>1 A contains formaldehyde and copper salts. Premix B and the bath itself should be handled as alkaline material. First aid in all cases should include flushing all affected areas with copious amounts of water. For further information refer to the OSHA 20 forms' ln any event the use of safety goggles, gloves, and protective clothing is highly recommended when working with any of these chemicals.
