This is getting to be a more common practice, especially with the application of a 2-D bar code directly to the board (via laser, ink jet,etc.) Some really major companies are jumping on the bandwagon because it also allows treating each board as a l

You will probably need to change paste. If I remember correctly the SMQ92J has a post reflow residue of 40%. This is one of the highest post reflow residue levels available. PIH uses a lot of paste which means a lot of flux residue. There are othe

| Hi there, | I'm actually facing a lot of trouble with PCB's presenting up to 3mm of bow /twist at reception i.e. before assembly. The PCB size is 220 by 230mm. The boards are to be assembeled SMD double sides with 05.mm pitch on both sides. In orde

I'll try to deal with the issues as you've presented them. 1. Blistering/delamination, shown in photo 2. The most likely cause of blistering/delamination like this is moisture in the boards. The moisture can get into the boards in multiple ways..

Hi William, well I guess SMT was invented accidentally when for what reason ever (be CAD related or PCB shop related) those PCB�s with no drillholes at all appeared in the assembly. Ah, you know these fella�s who are never short of a quick solution

UIC'S newer software has a category you can change to force a part to the back during optimization for this very reason. I think it's done in placement list. Example: A part coded 1000 will place after a part coded 500. I don't recall what it is

| Looking for a cross-referencing and part identification guide for surface-mount components. There is very little infomation provided on some of the components themselves, and we often don't have parts lists or schematics for items we repair, so ide
