A little late to the party here, sorry... Has the joint been verified as a cold solder joint? That is, visually confirmed that it looks like cold solder, and, perhaps, xrayed to confirm the solder status? X-raying may sound a bit extreme, but you'

Has anyone experienced a problem with conformal coating adhesion to IS-410 boards? We are having problems with one suppliers boards. IS-410 boards from other suppliers are fine and all FR-4 boards that I have looked at are fine. We are using Conap

I do not know of any standard recommended values for impact pressure in cleaning equipment. They act more as a guide when examining the various choices manufacturers have made for the spray flow, nozzle pressure, nozzle spray angle and other factors.

Your Head 1&2 have Chucks, is Head 3 a Chuckless Head? The Chuckless Head or Precision Head is the intended Head for use with the Centering Station only. Using Head 1 & 2 is not good as there is too much nozzle play. In your Machine Configuration is

I did one batch of low-density (0805 and standard SO chips) with excellent results. I then spent some time figuring out how to calibrate the mechanical alignment station (most of the calibration offsets on this machine were either zero or several mm

d0mino, Given the fact that the SLIMKic has built in wave detection, you can just make a pallet out of 10mm delmat material, and drill a couple of holes on the pallet for the wave detect T/C's (ports 2 & 3 for left and right). All the wavesurfer is

Well, everyone has provided good advice, but if you are looking for a wave flux that can provide much better dwell times and consistent wetting throughout the hole fill, without making adjustments to your production process, I suggest going with Senj

Dave, First of all, distilled water is not DI water. It is not the same thing. If you require DI water, you should know what quality is expected for your application. For example, for defluxing applications, generally DI water quality exceeding

Why? Just use IPC on finished solder joints as your guide. I've seen groups of people puts hundreds of hours into this task and then tell me a 3 mil stencil is all I need. After reflow, none of the solder joints meet IPC Class 1 and a lot of tombs
IPC is the trade association for the printed wiring board and electronics assembly industries.
