There are some common reason for capacitor cracking on my web page if you want to have a look. The document can be downloaded for your reference. | Earl, et al, | Boy things get old and cold around here fast. I promised more detail on my capactior

1. The jetting head flies very low to the level of the board. So, performing AOI function will crash the head. 2. AOI is performed close to the end of the line, after P&P or reflow. Are you planning to run the boards back-and-forth, on the line? 3. L

Many relays use soldered post coil terminatins inside the relay. In one case many years ago I found the SMT relay manufacturer used eutectic solder inside their hermetic relay. The SMT relay would fail because the solder balled up on the post, woul

When testing components on a PCBA, try to validate coverage for presence, correct, orientation, live, and alignment. AOI is not really great at catching cold solder joints and damaged components, and from my experience an X-Ray is only as good as the

I have never tried this and wouldn�t really even want to consider it. Epoxy generally cures at around 160c in a fairly short amount of time, solder paste requires much more time and a peek temperature of about 210c or more in some cases. Curing you

Our ICT Guy here at my company loves to use lots of via holes as test points - via holes which are 0.040" diameter, and spaced at 0.004" edge to edge spacing! He doesn't like to tent the via's either, so I always battle via-to-via shorts at the wave

You're a piece of work! Why don't you work for any of the major wave companies? So how does slowing the conveyor speed eliminate drying flux? And when you slow it down, what speeds it up to make you say "I lower the wave because I get shorts going

My SMT line does not has these facilities so would you please tell me regarding the UNDERFILL AND FLUX-DIP process and how they can be done? Thanks.
