Solder Paste Inspection Systems

Electronics Forum | Fri Dec 28 11:33:36 EST 2007 | realchunks

It really depends on several things. Is solder paste inspection driven from the customer? Do you have a lot of time and bodies to do solder paste inspection? Does it add value to your process? If you answered �Yes� to any of the above, then you a

Solder Paste Inspection Systems

Back in the mid 90s I used an SVS 3D solder paste inspection system. We used it as a stand along unit but it was an inline model. We would bring printed PCBs off the Dek 265 solder printers and check every 5 or 10 printed panels. They almost alway

Q1. What kind of labels/ink/sharpe can be used under conformal coating without disolving etc...? A1. While we're not familiar with the conformal coat you have selected, this might help. Label selection: The following chemically durable materials are

OT: Wavesolder Process Engineer Needed

Hello WaveMaster Larry, I think you are very well knowledgeable in wave machine or process. However, I think the reason why your former company won�t listen to you is because you also never listen to your people. I think you overlooked the saying �N

Hot Tear/Shirnk Hole>Will it happen on BGA joint ??

Electronics Forum | Wed Aug 06 08:09:57 EDT 2008 | davef

We agree that the squigglie part of the section of the BGA ball looks like something other than 'hot tear.' We'd guess that it is an inclusion, but it could be a sectioning defect, as you say. We agree that the majority of occurances of hot tear are

Line release of post reflow AOI and AXI

You are on the right track Ismir. Essentially however, as the programmer of the machine, I am the one that creates the PCB with the errors to benchmark the settings for the machine. No secret lab though! :-) Easy enough for most any AOI machine to

Landrex Optima II AOI

Hello Reese, I had an opportunity to look at the Yestech B3, Mirtec MV-3 and the Landrex Optima. Although I was looking at Desktop AOI Systems, Landrex was very persistent in getting an in line system in front of me at the time. The first machine I

Dominik, I have to agree with Andrew on his choice of Inspection Technology, but not the vendor. I looked at 2 of the 3 that you are asking about (TRI did not make my cut as I just didn't get a good feeling from them). I also looked at the Mirtec and

PCB Baking after Wash

Electronics Forum | Thu Dec 04 09:49:11 EST 2008 | lazzara55

Dear Steven: Often the recommendations for baking prior to assembly are derived from various J-stds. But J's currently concern baking moisture out of components, and fail to address the moisture issues of the PCB. Because of that, there is the IPC D
