Mike, I've tried the high side of the flux preheat spec with no success. I did just get off the phone with Electrovert tech support...... Get ready. This machine is configured with a Contour Plus N2 nozzle. We are not running N2. According to M

Hello Doug, thank you for the additional commentary, it has reminded me of another reflow recommendation that I'd like to make in general for readers. It's not specific to O2/N2 in ovens but in the method for creating and managing profiles for numero

Hi: I'm looking for input from anyone who has experience assembling the MLP package on PCBs. We are experiencing solder opens after assembly, and I'm curious to see how others are processing these critters. The part we are using is a Semtech SH3000

OK, disclaimer; I'm a salesguy, but I was a process engineer for quite a lot longer than I've been in sales. Your question is very vague, and may be difficult to answer. There are many ways to configure AOI to inspect solder, but as has been pointed

Hey Jason- I saw yer post on Technet as well. First I agree with you 100%. It is kind of funny how Capital Equipment Mfr's can lay off Service guys, Apps guys and Customer support Guys (Guys = men/women) but charge more $ for registration fees for

Amen Jason- I have been fortunate and worked on both the Customer and OEM side. Regardless of who, what, why, when for the machines A customer is a customer is a customer and all should be treated on an equal level (unless that customer becomes a li
