Passwords for the ZCR / QCR did change with the version of S/W. I believe that from version 2.9 onwards the password to start the S/W from the DOS prompt is "quad" [all lower case]. Pre version 2.9 please type "zcr" [All lower case]. This will enable

IMHO, depending on whether its a regular run model, or a properly designed/setup pilot run model, getting a mean 75%-95% First Pass Yield (FPY%) is possible as a benchmark target. This is derived from your manufacturing history capabilities, and requ

I have encountered problems with a 90/10 tin-lead plated SMT component wicking all the solder paste off the pads on the substrate. Worst, the defect occurs randomly - adjacent leads may have 'good' joints, though heel fillets are poor. The solder pa

Smart Sonic has an entry level component to our StencilScan AOI system called the Assembly Module GT. The Assembly Module GT is low cost and will get the job done. Plus, the Assembly Module GT can be upgraded easily to the other Assembly Module produ

My boss who always like to read smt related mag,pick up what he can or don't understand from the article and blame all quality issue on engineering. We are seeing solder paste residue all over Juki printer equipment,on the floor,etc.This is mainly du

Barney, We currently have 3 Contact Systems machines, (1) C3AV and (2) C3AVXs and I can't say enough good things about the machines or the support. It has always, always been there since we started dealing with them in 1991. The Service Dept personn

Component manufacturer often have recommendation for pad layout and process setup. This should be used as a guideline to help You to set up the process. Exactly what type of component is this, uBGA? We populate 64 I/O uBGA's on our pcb's with 0.3 mm

Hi All, We are producing a veriety of RF related PCBAs in which we see Unsolder/Mislaigned on a regular basis. In these baords usually one of the pad is connected to a signal trace and the other pad is connected to very huge ground plane. This gro

Hi Dave, Thanks for your reply. I have tried getting the design changed from the customer but they cannot provide thermal relief as this changes the RF performance and they cannot afford to do that. As for profile it does reach the reflow tempera

Joe- You confused me In the subject it has SMT and in a posting you say Through hole components. I was incharge of getting equipment for a research and teaching facility called ACI (Some know it as the EMPF). I was tasked with getting equipment at n
