We have a 1.6 mm thick automotive PCB board of size 35x70mm. One of our vendor has given us a batch with lesser soldermask thickness 5~8 microns. Will this affect the circuit board on a long term. What should be standard for the soldermask thickness?

The Accuflex is a machine that MPM has evolved into from a SM Tech platform. They purchased the product from SM Tech. The man who designed the platform designed Dek printers; essentially the Accuflex is a DEK platform. If you are looking for a UP

I would like to hear from anyone who has ever successfully spliced conveyor belts, or who know's where I can get my hands on a splicing iron. I have belts that are broken or just need lenght modifications. please let me know if anyone does this and w

what type of belt is it and what material is it? round belt, flat belt, etc... if its from a PCB transport conveyor or other PCB handling system, I recommend you contact the OEM. I have spliced belts before- rubber round belt off old Fuji loader and

If the flux is already eating thru Cu it must have been some time since the boards were soldered with the OA flux. Ionic contamination testing (with OmegaMeter or IonoGraph)can be done to find contaminated boards and cleaning the boards can be done

Yes, the OmegaMeter and IonoGraph are test equipment to measure ionic contamination. Either of those units should enable you to sort your inventory boards. for more info about this equipment, go to: www.cooksonee.com/products/scs/CoatingSystems/Ionic

Yes Ion Chromatography can when using a isolated extraction system called the C3 tester. Please email me or call of-line and we can show you what we have done for others to not only idendity the flux cleanliness levels but to qualify the cleaning pr

Why would you have troubles if and when you switch? Isn't that the point of materials evaluation? Understanding the impact and material capability BEFORE "betting the farm on it". I would never stake my career on a solder paste without an Engineer

AXL, you could be right! I personally didn't switch they did it after i left. Is it possible that indium might have changed in the last couple of years? I remember Indiums specs stating 40% post residue? This was quite a bit higher than some othe

We received some parts from our stores room with out a part number. We have 2 to choose from one being a 5% and one being a .1%. Does the color of the resistor mean anything? Just need some help on this. Thanks.
