We've seen the same thing - leads of QFPs not as strong as we'd like them to be. In the past 4 years no problem, this Spring they start failing. Touch a solder iron to it and it solders fine. After crunching some data, we found that both QFPs fail

The process that burnt the tips up yesterday was hand soldering/touch up of lead-free assemblies. Not even assembly, but just touching up boards that we've soldered on a solder pot...which will lead to another question. We're using SAC 305 WS482 3

It's worse than just using the test equipment manufacturer guidelines. Along with that, you have to deal with each of the test fixture fabricators' preferences as well. What this boils down to is a negotiation with the test engineering group as to w

Hey guys, just joined the site and I'm looking for some help. In our coating department we are running a Asymtek C-740 with a Jet and film coater. The coating that we are using is Humiseal 1B73 acrylic. The problem that we are having is that the C

You stated that you are producing Class 3 boards so I assume you are familiar with the IPC standards.To answer your question directly, I'll refer you back to the J-STD-001. Clause 12.1 states "12.1 Rework Hardware defects shall [N1N2D3] be documented

I'm trying to get an '07 Accuflex into production and I seem to have a small problem. When trying to calibrate the zero pressure point on the squeegees I drive them down until they are touching the stencil and once they touch the stencil they run ou

hi, there is an IPC standard, IPC-A-610 - Acceptability of Electronic Assemblies. According to this manual, solder in the bends of a lead does not matter, but solder touching the body of a component is a defect. I cannot find a specific reference in

I've put down a SOT223, close enough to your 3pin transistor, in the same situation you have. The large pin was to be soldered on a large exposed ground plane in the corner of a board, over 2"x2" exposed area. We left the paste file as is, so where

There is one thing to be checked too. That is to make sure the nozzle not going too deep when lower to pick up the part. I found a lot of picking errors issues are due to nozzle going down too deep into the pocket. If it does, it pushes the component
