I agree with all of the previous comments. 1) Here are a few things to keep in mind when cleaning with water. To effectively clean, any liquid must wet the surface. By itself, water has a surface tension of 70 dynes/square cm. This is relaively hig

we bake boards 80~120 deg-C @1hr, after in-line DI wash. oven setting to 90 deg-C, as +/-5 deg-C, tolerance against door open/shut fluctuations = "temperature loss". If anyone has evidenced procedure, that shows no need for baking, pray do share wi

We're not sure what you mean by temperature sensitive components. From an assembly process stand-point, every component we use is temperature sensitive to one level or another. More specifically, some of our products use polyphenylene sulfide (PPS)

If you�re running chemistry in the wash, the wash temperature will be influenced by the chemical manufacturer�s recommendations. Typically, wash chemistries recommend operating temperatures between 130F and 150F. If your application is straight D

Peter: Questions are: * From your pictures, the white residue appears to be only on the solder mask. Is that correct? If not, what is the location [eg, solder, nonsolder/nonmask areas] of the residue that doesn't show well in the pictures? Further,

The recommended wash concentration for stencil cleaning with VIGON SC200 is 25% and this should be confirmed using the ZESTRON BA-20 bath analysis kit. Additional cleaning recommendations are: Wash temperature should be approximately 25 degrees C. /

Just from my recently acquired experience working with wash chemistry. Some will have issues with foaming as the concentration of wash chemistry goes down and the temperature of the wash goes down. Over a few washes you may be seeing a reduction

2) Open time: A 15-minute queue between paste, place, and reflow SB fine, assuming humidity is not too great. 3) Wash temperature: Yes. A wash temperature of 130-140�F SB fine. 4) Reflowed board was left too long prior wash: Are you washing: * After

Should drying be done after aqueous wash? If so, how long and at what temperature?

Additionally, increases in temperature can increase the water's rate of reaction with the flux. Sometimes, only a 5 degree change can make the cleaning difference. If the flux inconsistently presents itself, then the likely cause is something in
