I have recently signed onto a company with very little board assembly experience. I am trying to develop a process control and continuous process improvement program for a new surface mount line, but have run into several people who are not really i

Hi, I work for Nortel and here rework BGA'S we use DRS22 rework station and CRT 2000 X-ray inspection. The main problem is put again the BGA on the PCB because you need reboling the PCB and you could damage the soldermask. Talking about Air-vac is ve

Handling requirements of all classifications of moisture sensitive devices is found in J-STD-033. It really isn't an issue for most parts unless they're going to reach reflow temperature again, which is unlikely unless you're removing a nearby compo

That's like asking the IRS to do your taxes for ya. Once they're in your building, they will not leave until they go thru top to bottom. Remember, EPA Field Investigators are "supposed" to find things wrong. They may not find any thing wrong with

Hello, I have just installed the demo version of GC-Powerplace. Could anyone here walk me through the process to generate pick and place file from gerbers? I don't have solderpaste layer. All I have got is signal layers (top/bottom), soldermask, sil

Although we do not have any soldering issues with our OSP PCB's, I am trying to establish clear rules with regards pcb storage and shelf life. Our PCB's are supplied in metalised moisture barrier bags but without desicant, our current rules as follow

The quick frame does work well with the DEK 265, but we feel that tensioning is user dependent and introduces variation into the process on an operator to operator basis. Also, because tensioning occurs only on two sides (instead of four) this also i

Well first off I wouldn't evaluate paste for a wave process. I would use solder bar instead. Flux - top side fillets and no shorting on the solder side, does it clean well after processing if using water soluble flux. How wide is the process win

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
