Hi Jason I think Wolfgang has this one nailed. If it's the same four pins every time and nothing changes this, even rotating the board 90 degrees, then you're probably going to find something like a ground plane connected to them. I don't think sol

I have 15 very large backplanes (.156" thick Au plating) that the ground pins of a high density thru-hole connector were not thermal relieved in the artwork. As a result we are unable to solder the 8 pins that connect to the ground plane. We know t

0.0006" LT Total pad height = Thickness of ( Copper pad + OSP ) = 0.0014" + 0.00000157" = ~0.0014" (You must be using an organic solderability preservative (OSP) or Electroless Nickel immersion gold (ENIG) because 0.003" tin/lead or white tin would

Jason, First, check with the manufacturer of the flux you are using. They can tell you what board topside temperature range the flux is designed for. Some other info is needed for the residue part. Is it showing up on the same board, or different boa

First of all I would like to thank you for your candid comments on this subject. ECD listens to its customers and values their input. Yes, our experience shows the coupons have a 30 to 60 run life depending on application. This works out to between

Kathy- Greater than 88%. Is that 3-D Nicolet? I had a conversation with Arline yesterday, she told me about your trials and tribulations with re-balling. I would like to suggest you try micro-stencil instead. If your BGA rework center has the capabi

Ashok: Couldn�t find that part in IPC-7711 either. I was just remembering that proposal from that thread mentioned. So you are still in that position I was at that time. Looking into IPC-D-275 (I have to admit that I have only an old issue in my offi

I'm working on a project that requires that I analyze a signal from the parallel port of my computer and use it to turn on relays. There are about 19 relays to control, and I designed all the gates to get each one on, but there is a problem with keep

Dave: The main part of your machine that VOC-Free fluxes attack is your spray fluxer itself. If you haven't already, you'll need to purchase a spray fluxer that's designed to accomodate water-based VOC-Free fluxes (i.e. made of stainless steel with
