First, determine a standard to follow. IPC/EIA J-STD-001C "Requirements for Soldered Electrical and Electronic Assemblies" is most current for electronic assemblies. Second, by your customers spec. determine which class of the standard to apply. Use

All, Does anyone sell a safe and effective way to connect a DMM to building ground via a power outlet? Personally, I'm comfortable using a banana plug, but the people that are going to be performing this task may vary in electrical understandin

I need a technical specialist to turn-on, trouble-shoot, modify, repair, and test the power supply prototypes at the printed circuit assembly and instrument levels. This person would be involved in setting up both manual and automated tests, making m

If it's not adhesive, try an ESD-type ionizer. The objective of an ionizer is to eliminate surface charge on insulators and on isolated/ungrounded conductors. Practically speaking, the action of an ionizer is to drive the voltage on the surface of a

5 Steps to Eliminate Bridges: 1. Establish (wave) Parallelism First and foremost, you must establish board-to-wave parallelism. This is the prerequisite to any wave solder process control. For an understanding of the power of this approach go to ht

Selective soldering machines are a good way to "finish automation", if the design of the PCB is conducive to the application with just a few components to solder. Your points are good. A decision matrix for selecting a machine might also include:

Kel- My first impulse is to tell you to go ahead and try it your way. We all need to learn from our mistakes to find the right way. What you are proposing is called a "smoke" test. As long as you can keep the smoke inside the device, in your case th

Our first pass yield across all our products is above 95% but we include anything that does not meet IPC standards. Probably 75% of our failures are not electrical. AOI is a great tool to get a consistent measure of your process. I dont know how anyo

| Hi | I have been conducting my first reflow profiles. Most of the texts that I have read suggest soldering the thermocouples to a populated pcb. I am finding this very difficult. I have been using a high melting point (Sn5 / Pb95) solder and the
