One thing I have run into when placing cap's flush to the board is blow holes due to the plastic sheathing used around the cap. It would form a gasket going through wave and exhaust out of the holes therefore blowing the solder out with it. This cap

I have posted earlier on a UIC Radial inserter machine. We have the machine running after repair of the CnC head. However, I now have a process problem with a board that has 256x3 LED parts (768 LEDs in three colors) where only 50% of the LEDs can b

Hi Dave, I am agree with you,but one of my customer want to know the difference in terms of rework/Quality,if we go for Glue process in place of solder paste and want to see some data We have board ,which have Through hole components and smt comp. on

Hi, We're going to migrate our boards from through-hole to SMT, and I'm dealing with the PCB layout. I've found a lot of references for fiducial marks but none of them states if components can be placed beyond the marks limits or only within the are

So it's a C-n-C clearance issue? Could you go with the other cutnclinch unit...which ever you have, get the other one (one's right angled, one's offset at 45�)? Yeah, I know, they're not cheap. Other than that, hand place some of the SMT in chip bon

We manufacture low volume, high reliability assemblies (class 3) that are conformal coated. Up until now we have been cleaning after SMT, then after through hole, then immediately prior to coating with test, formal inspection, etc. between cleaning p

Hello once again! I am having a problem with a 24 pin connector bridging on the wave. We use very similar connectors on other PCB with zero problems. This connector bridges in the same place on the same pins. It forms like a little block of four
