My understanding is that you get a reading that's the average of all of the jumped points if you jump tc wires with conductive tape. If you're doing multiple parts on a board with varying masses and don't control the attachment method (i.e., how mu

I have used KIC data acquisition equipment for over 11 years. Slim kic, sideKic and Kic2000, prophet etc... The 9 volt battry changes in seconds. Gimme a break. The internals don't reach 54Celsius. If it came down to batteries, I bet KIC would t

I worked for a EMS who makes Medical Device Electronics, and yeah, the FDA's methodology for validation is a complete cluster-fudge! They did it on the principle of...does the shop air going into your equipment REALLY 80 PSI...or is there REALLY 220

MikeL, I came across your post. We are also a small company looking at rework systems for BGA/QFN/CSP. .5mm worse case pitch. We had a PACE 1700 on trial and we found it clunky and unreliable. We also evaluated a PDR 410 system and found it better

Hi Russ, Just a quick note to you the assembly houses, You say your transition will be the easiest, I would have to beg to differ after working with several CM's and working with there Wave solder lines and finding compatibale fluxes that will work

I recently finished analysis of no-clean fluxes and Ionic contamination and cleaning processes. The results were eye opening. Summary: If you clean a no-clean you better do a good job. Many no-cleans produce a "waxy binder" to encapsulate the tro

You have 2 groups giving us 'evidence' here: 1. the research companies who will do anything to scare us, just to make sure more research will be done, if they said everting was fine they'ld be out of a job in a sec. Ex: look at that paper, a leaded

CGO Assuming your system is performing well here are a few ideas to help out your profile.... - Pull the material spec and ensure you are meeting the requirements for times and temp. Many times the material will allow a mild soak of the board prior

Hi Experts, We have requirement from our customer to control the PCBA flatness at 10 mils diagonally. Weird but this is the requirement due to the need for some through hole pins (spreaded acroos the board must touch the copper sheet while they are

Yes, different pastes will cause ovens to become "dirty". I believe you are talking about flux build-up. I've switched from one paste to another based on sample studies, only to find an increase in oven cleaning. During most solder paste evaluatio
