Anyone with selective wave experience ? I'm buying the Selective Wave machine and trying to workout the comparison matrix. Can someone tell me what criteria should I look at when listing down the matrix ?...things like, min clearance to the high prof

That's what I was thinking when I started the project. Turns out for each part the rendering is an OLE object. Even if I was able to write a script to access the package editor inside CircuitCam I wouldn't be able to create new files. I assume this i

Hi, Heard about flux encapsulant - a compression-flow flux and underfill product for flip chip assembly. It eliminates the need for a separate underfill operation. Does anyone has experience in actual production run? What is the possible effect for

On SMTnet, we've discussed the the frailties of controlling paste height, when volume is a more telling measure. Sometimes if you seperate too quickly, the paste tries to stay attached to the aperture walls. This creates a 'U' shaped deposit with r

I would like to know the Stated Specification for PTH size tolerances. Or is there a generalised acceptable limit?. We have some PCB's with hole sizes that I consider to be way off what I would deem acceptable, ie Finished hole size should be 0.89mm

Don't throw away the tapes ! We use vast quantities of component tape while testing our P&Pmachines. And mind you, we are normally not particular on what values the components have. ( For some tests we don't even need components in the tape. Its just

I am sure the QP-132 is a more stable platform. It is a Fuki after all. My big question is why not X2 CP-6 machines. I mean you can tell by resale value of the FCM Vs the QP-132 that the QP-132 is a rock solid machine but, for such cheap money two CP

Agreed that the FCM has been the choice in the past...but have you seen the 4797S HSP (TCM X100)? Usually (2) 4797S's can replace (1) FCM for about the same purchase price, and only a slighly larger footprint (consider the cost of ownership as well..

Problems using NC in RF circuits are peculiar. Depending on the situation [ie, circuit layout, frequency of use, processes used, materials, and what not], a particular NC flux may not work with a RF circuit. Various NC fluxes leave different levels

I'd tend to agree with what the others have said. Check the basics, board supports, setup, wiper paper working correctly. If it's a humidity issue, try taking some paste, place it on a chem wipe, and roll it around a bit, which removes some of the mo
