My first and only thought is how old are the parts? Strange things happen to some materials over time, especially if they're stored in environments without significant climate control.

We are in the process of updating our SMT area and I need to clean my boards. In my research I have found out that if I choose the ultra sonic path I need to make sure the cleaner uses a sweep frequency system in order to protect the SMT parts. Can s

Looks like you have a great wetting of your paste :). Once body has been in contact with molten solder, the package could suffer damages on the body(outside and inside) and on the circuitry inside. It is considered a defect. I have seen that before a

First of all, sorry for my bad english (I'm german)!!! We have the following problem: we assemble 6pcs. smd 30pin connectors on one of our boards that we produce. These connectors have a top cover, that the pick&place machine can put it on the board

Thanks for the reply, Russ. I looked at the Air-Vac web site. I am looking for something that is a lot more basic than their machine. I had seen a small table top wave machine at a customers shop a few years ago. It had a pump and different si

We are looking to purchase a table top batch oven, with nitrogen, for prototype work on various PCB assy's - some with BGA's. The intent is to simulate a multi-zone production oven profile - and we kow that an exact simulation is not possible - just

I run have a small SMT line that we run small engineering samples runs on. I have a 625 pin BGA that has a metal top and I have never ran one like it before. I am not sure how it will react.... will it pull the heat up away from the PCB or just heat

I have some CERSOT-23 transistor packages with castellated terminals. The 4th lead (drain castellation) is electrically connected to the top of the device by the castellation. The castellation goes up the ceramic body and contacts the metal package
