Flexi boards and uBGA

Yep, Book a holiday and let someone else sort it out. Otherwise e-mail me and I'll talk you through pallets, rigidisers, printer tooling, spray mount, Kapton tape, local fiducials (panels can strech & shrink) etc. Oh, yeah - for the connectors you

SMD Inspection and Touch-up

Electronics Forum | Fri Jul 23 10:47:31 EDT 1999 | Mark D. Milward

There is a practise within the industry of an Inspector inspecting a board, and that same Inspector performing touch-up. My opinion is that the Inspection and Touch-up operations should be separate functions whereby the Inspector is not performing th

Dye and Pry

Hi All, One PCBA failed test after went through the Shock Test(Vibration) and suspected to be BGA solder ball crack. We performed dye and pry and found PCB's pad lifted with red mark ink penetrate pad underneath, what does this mean? Can I say the

COB and wire bond

Electronics Forum | Tue Jun 04 19:33:16 EDT 2002 | rob_thomas

Dave's estimation is pretty conservative but there is a lot of equipment out there and a lot of people happy to make a sale.Implementing both mentioned processes it's difficult and time consuming .Even if you get good training from whoever sells you

Circuit cam and mydata

As everyone else said, if you don't have CAD, it's a pain to digitize the gerbers. So much so that we only did it once when I went to CircuitCam training. After you digitize the gerbers, you have to merge the BOM with it. And you have to tell it p

PCB Identification and Tracking

We use both labels and lasers to mark our boards. Since implementing the lasers, the downtime attributed to bar code labels on those lines have dropped to virtually nothing. We still have problems with the labels wrinkling during reflow making read

&gt; We unfortunately use GERBER data to digitize <BR> &gt; boards more than any CAD. We are CM and many of <BR> &gt; our customers do not provide CAD. With some <BR> &gt; Legacy products, we still use 274-D Gerbers

via tenting and pluging

Via filling methods are: * Tenting * Plugging * Capping * Flooding Tented Via. A via covered with dry film soldermask; the via is not filled. When tenting from both sides there may be issues with trapped air that expands during mass soldering. Plug

Inspection and splicing

Electronics Forum | Tue Aug 21 08:34:03 EDT 2007 | rgduval

We have the same problems with cut/tape parts. But, we specialize in short-run prototypes, so I don't have much of a choice but to deal with it, and find a way to make it as easy as possible. We just demo'd a splice tool from Sierra Electronics (ww
