Some people involved in PCB assembly process claim that SMD components reflow soldering problems are often caused by traces running under a component. According to this claim, trace (or any copper) covered by solder mask and placed under SMD componen

Have your designer place the via on the edge of the pad, centered and cover it with soldermask. If this is a leadless capacitor or resistor-style component, the corresponding pads will need to partially covered with solder mask to match the via in p

Q: The question I have is do they wet in wave solder, and if they do, why does it matter what happens to them in reflow? A: Yes, but somebody here don't agree with me that the glued part need help from wave to get the good wetting. They are wrong

Thanks for the acvice, Dave and John. Like I stated above, I didn't feel comfortable with changing wave parameters since I knew that we'd be compromising our wave quality. I'll try the peelable mask thing, reprofile, and let you guys know what i fo

We've got the same problem here, what we do is to apply peelable solder mask around the connectors or the exclusion zone. But be carefull! Sometimes the soldermask get inside the connectors and you can't remove it so you have to change it. Another th

Tony: You have choices: * Hi Temperature Tape: Go with Wolfgang ... too tough to control. * Selective Soldering Pallets: Some like 'em some don't. A lot of your success depends on the pallet fabricator. * Screenable Temporary Solder Mask: Wol

Mrduckmann2000: Why do you want to do this? * Removing a non-washable / peelable temporary solder resist [TSR] is going become very tedious, because they do not release well from small / tight / isolated features. * Clay from washable resists will

Hi Stephen, The component falling off is the component that had glue. the component witout glue is being covered by masking during wave. What is the meaning by populated the part and cure it? is it run with solder paste profile or glue profile or yo
