Hello everyone, hope everyone is doing well. I would like to know what should i look for while purchasing an X-Ray machine for SMT production line. I am looking for offline x-ray machine and budget below 90k usd. It will be used to inspect BGA, QFN a

We have a Glenbrook Jewel Box 70T, purchased about 5 years ago, Think it was around $60K quoted price (we traded in our old Glenbrook for a discount), Software pretty basic, can store images and has some graphics and image processing capability. It h

Hi, I just saw the new NXT machines at globaltronics in Singapore, and mostly they are faster. However what was interesting is Fuji shows a prototype of the new XPF machine, but it was called XPF-W which handles really large PCB's and uses the sam

Since we are on the topic, What we do over here, is to get SMT Technical to machine pick&place "sample component layouts" onto double-sided tape, which in turn is placed onto an actual PCB... QA will take that double-sided tape sample, and using an

Hi everybody, First of all, to have process under 100% control you should have AOI after every active process in the pcb assembly line : - Post printing (2D or 3D Solder paste inspection machine); - Post reflow; - Post selective(wave solder). It i

Hello sir, Limits in SPI can vary a lot, also depending on finishing of the pcb. For example 170% volume on an IC (assuming is fine pitch) can be okay for ENIG, but very bad if HASL. For are I would recommend that you use either 50-130, or 60-135 max

Cheers Rob, I thought that I wasn't far from the true answer....I figured that if we were to use a "first piece assembly " quote to get a first off through smt production, This would include start to finish process....e.g Programming to first board

It sounds as if you have your AOI set up off-line, and you're "AOIing" a sampling of the PCBs produced. If that’s the case, then the responsibility of who drives the inspection really depends on how you configure it. If it's based on the number of P

| How are you inspecting pcbs post-reflow, are you inspecting all or sampling. The type of assembly involved would be mainly chip components with a mix of actives and a few 25mil and under pitch. | If you sample what are your fault rates looking lik

You would be suprised what you can see with even a simple Xray machine. The engineers upstairs wanted to see if the xray could confirm there was an open via on a thin dense board with several layers. I thought (but didn't say) no way. But with carefu
