Can american R&D cooperate with customer and industry needs? can the education system produce world class engineers? Can freedom american style even remember what cooperation and team work is? It's a dog eat dog out there and eveybody is out to prote

We are using 1mm pitch BGAs with a great quantity of via(s) under the component. Very shortly we will be placing CSPs with .65mm pitch. Our via(s) are solder masked, however we generally have a percentage of them that the masking is thin enough that

In general, I always consider machine support a key factor when buy equipment. Being rude on the phone is a part of it. There have been several times when I have asked the service guy why he's being such an ass to me - and most times they tell me w

We have an internal debate whether to calibrate equipment using K-type thermocouple made out of : 1) fibreglass braided, with a 482 deg-C peak-measurement properties? 2) teflon FEP(fluorinated Ethylene Proplene), with 204 deg-C peak-measurement p

Hi. Does anyone out there know of a way to calculate the surface area of populated PCB's? We build many different types, and until now have been using a water displacement method, which I believe to be fundamentally flawed. Our technique is to drop a

No need to make rocket science out it. Buy an AOI mchine. If that's too expensive, scrap a board to use as a sample. Can't do that, use a digital camera and snap a couple pix of a good board and make some kick ass work instructions to use. Can't

Tim, have you considered how efficiency software plays a role in the matrix? Most software from equipment suppliers tends to be programming driven. I have run across a software product from Timms that does an excellent job of controling things lik

Steve, Dason has valid points here. dun listen to what supplier's say about paste lying on the PCB pads able to be exposed at ambient temperatures for 8-24 hrs? that will never get approval for Class-3 type of customer auditors. (Would any serious

Your board fabricator can tell you how they want you to specify boards that do not have solder on the fiducals on the rails. They probably do not need some BIG stinking drawing change, but can operate from a letter. [And even if you run the change
