Depending on your D.I. system, your maximum temperature concern may be at what temperture it returns to your D.I. system. Hot water may foul you set-up very quickly. As for maximum tempertures for parts, your biggest concern should be drier section

We always apply solder paste to either the PCB pads or the BGA balls. I have found that only using liquid or tacky flux does not always ensure proper wetting of the pads. Also The BGA sits closer to the PCB making cleaning and endoscopic inspection

I am currently working on a manufacturing flow where some PCBA are processed with reflow oven (after being baked before processing), then cleaned with bath, then passed into contaminometer, passed into AOI. The point is after all of this, if AOI dete

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've been using S100 total cycle cleaner for years - diluted in ultrasonic bath for about 10 minutes. Blow dry with medium psi nozzle. Works great.

| Hello everyone, | We found many cylindrical diodes missing during SMT process. Could someone tell us how to prevent this problem? Is it effective to change the shape of stencil apture or reduce fan speed in reflow oven? Thanks in advance. | | Gyve

Beej, The tool supplied works well as long as the bath is up to temp and the nozzle tip was not cross threaded when fitted. Did you apply a small amount of the anti seize paste before the nozzle tip was fitted? I have seen dry tight threads if not ap

Our cleaning process involves the assemblies being completely immersed in the water bath of the ultrasonic cleaner. The assembly has a QFP44 on it. Customer stated that when these assemblies have been cleaned with water in the past (at a different

Steve, We use the 955 version for printing with the DEK Pump Print process on two lines in high volume. We clean the stencils in an ultrasonic bath with Hydrex A+ I think diluted in deionized water at the end of 2nd shift. By startup, they are dry

Hi All We are looking for not expensive solution for misprint PCB cleaning for both one and double side assemblies. We have tried different ways and cleaning solutions like: IPA, Vigon Zestron SD300, Vigon SC200 by deep the boards in to stainless ste
