We have a PARMI SigmaX SPI (Solder Paste Inspection) machine, right now I'm trying to understand about parameters of the machine. I know minimus, Maximus, and warning values need to be defined. Height value understands that can be defined by the thic

we looked at the mirtec when we were selecting our AOI machine, it is a good machine, we eventually settled on an MVP GEM, comparable price but very powerful machine, we place down to 16thou pitch and 0402 and the MVP's solder joint inspection on the

We have evaluated (in-house) the following machines: Agilent SP50, CyberOptics SE300, Siemens OS. We have also evaluated the MVP machine and the Orbotech machine off-site. Best bang for your buck??? CyberOptics by far! Better Gage R&R, better standa

I have done it different ways on different equipment. 1. Remove alloy one from the machine. Add alloy two only. and use it.For next board, do the same. 2. There are machines with separate sections for PB and PC-Free, so pots are away from each other

Well grant just to let you know i feel your pain. I've been wavesoldering with sn100c since January and let's say i'm still learning everyday. Some of the typical causes of bridges are not enough flux when the board hits the solder. Also it can be bo

CK: I hear you about pads. Most secondary side SMT pads are primary side SMT pads that are on the secondary side. This only matters when boards are wave soldered. Rather than changing to larger components, consider a bigger fight than that ... ge

Russ - I agree with Dave and Wolfgang that the boards are the top suspect. The idea of "rework" from Gold to HASL sounds scary. Are you sure the Gold is electroplate and not immersion? Resolve that and then check the archives for "dark pad" or
