Talk to your buyers about forcasts. How do they know how to what to buy? They should be able to tell you what parts are going to be used on all the upcoming assemblies. Just make sure you don't get a purchase requirement report. That wouldn't inc

I have some suggestions. We have been fighting bad fids for years. Some things we have tried that have helped is: 1) Look at your relief area around your fid. Does it butt up against the solder mask. We allow 20 mil around the fid as a relief ar

That you can get good solder flow when hand soldering seems to indicate that the temperature of your solder pot is too low. Still, I'm uneasy that you see gold on the pads after passing the board across the solder pot. Gold is so thin with ENIG. So

We are currently using an ACE K.I.S.S. 104. We used SN100 solder with AIM NC265 flux (no clean, alcohol-based). Also, we use topside preheat at 100 degrees C and a 6mm nozzle (as big as we can go with this application). The PCB has a matte finish as

Here’s what we seem to know: * There’s a problem with voiding in the solder connections of SMT capacitors * A void is an open area caused by air or process fluid that is trapped within a solder connection * Voids are an allowable condition as long as

I have run 0.031 boards. One of the things you may want to look at is the speed of the oven. With 14 zones you may be going to slow with the board which could be the reason your boards are starting to bow. You might also think about adding stiffners

We agree with all of the previous comments, and would add the following: Warpage is generally caused by excess moisture in the raw boards. Have you tried baking the boards prior to assembly? We had this issue on a simple 4-layer board, and found t

Hi, my supplier is using the same Aqueous machine to clean the boards for 2 different customers. My product uses the chemistry of leaded clean flux meanwhile the other product uses the chemistry of lead free with no clean flux, however that product r
