IPC-TM-650 is a works well. Ionic conductivity is a good rule of thumb but I prefer ION Chromatography this will help determine the residues left behind from the fab process. There are a bunch of ways to determine solderabiltiy- Wet Balance and SERA

The connectors are well within thier specification,and are also checked for misaligned and damaged pins , as regards the cross-section results, all holes are correctly aligned and are well spaced within their tolerance of +/-0.005 (a couple of isolat

Research was done into the deflection of a totally unsupported (topside) PCB of 0.050" thickness. A dial indicator was placed on the surface and the tooling was set. The deflection ranged from 0.005" to 0.007". This is minor when you consider th

1) We have been using the replacement tips regularly. We, also, purchased a precision pin gauge that we are using to clear the C14 nozzle without risk of stripping it out. 2) Right. However I've pinned the 0402 centering level down at -25um.

We have a Versaflow 40/50 and ours is setup like this. We have out nozzle test position set so that in the Z axis you are 3.8mm away from the pin. Used feeler gauge Then you can set your gradient per nozzle. Start with a number then do a wave offs

Electronics Forum | Sat Jul 19 12:22:55 EDT 2008 | operator

Are there any softwares OR functions inside of the softwares that allow a designer that is creating a very large complicated wiring diagram with say....many terminal blocks and connectors etc... to run a point to point check on his drawing? Bascially

Morning all, Has anybody done any pin in paste job with a dispenser? I read somewhere that the needle i.d. should be slightly larger than the hole diameter, but with holes of 1.4 mm I would have to work with a very large needle indeed. How does past

How would you mount a surface mount chip onto Perf board? I am doing a project for school and one of the chips is a surface mount, but everything else fits in Perf board. Any suggestions? Thanks Matt- Find some fairly stiff wire, the correct gau

Agree with PDE. We have two GSM's and we get this error often. Palm down e-stop when you get this error message. Machine will drop nozzle bank down after doing some segment repairs. Open covers and make sure nozzles are seated in reference to ali
