I'm am trying to narrow down a packaging solution. My requirements are as follows: 40um Line Width/Space Capability (or finer) 4 layers low loss at mm-wave frequency (75 GHz) substrate size up to 40mm x 20mm I do not have any demanding via requirements as the majority of critical signals are on the periphery of the die. I have been able to find a lot of journal and white papers online that suggest these capabilities are very achievable. But I have had a difficult time compiling a list of vendors who offer this capability. I am not tied to any specific substrate material (silicon, LTCC, LCP, etc) as long as it has acceptable electrical characteristics at 75 GHz and is compatible with the thermo-compression bonding required for Cu pillar packaging. I would appreciate any recommendations on vendors who can achieve this so that I can attempt to determine a cost optimal solution. Sat, 22 Oct 2016 13:37:46 GMT Poor Wetting On The BGA. Hi All, Currently im seeing a cold solder/ poor wetting underneath the BGA Ball as i shown in the attachment. From the attachment you also can see one ball with poor wetting and another ball with a good wetting. When i checked with my re-flow profile temperature, the peak temperature of a component was on 253*C. I was in doubt why the one of the ball found poor wetting but another ball beside it has a good wetting? Have anyone have encountered this this before and may i know how you resolved it.

Fri, 21 Oct 2016 02:20:15 GMT Component Missing Hi, I have a FUJI CP4-3 machine that is experiencing issues with missing components. The machine keeps on running even after many parts are missing and it releases the board thinking it's complete. For an example, say there is 200 components to place,it places 190 and misses 10. The missing components are picked but are placed in the collector bins and the board is released without any notice of the parts missing. ( the component it misses to place is the Register-0805 and is a repeated component) Thank you A1 Thu, 20 Oct 2016 16:13:05 GMT black fiducials Hello everybody. I can't get black fiducials when laser-cutting a SMT stencil. They are grey or beige but never black. Can someone help me? Thanks!

Good day I would like to know if the Quad 4C keeps a register of rejected components in a certain period of time, like " X components rejected from feeder Y" or something like that.

There's a SMT manufacturing plant in Algeria which requires technical support / training. The company owns Sony machines such as SI-G200. Does anyone know any technical company that support this Algeria plant aside for JAS-SMT? Their concern is that these technical companies requires advanced payment which Algeria government doesn't support. Other words, Algeria plant will pay after the service is done. Kindly assist & advise. Thank you. Tue, 18 Oct 2016 20:58:39 GMT Sony SMT Machines Support in Algeria Tue, 18 Oct 2016 20:52:55 GMT Placing RF shields on PCB's.

Our company recently bought a Samsung CP40V pick and place machine. It works very well, the software is intuitive but we have one problem. Is there a way to manually set fiducial position after machine failed to recognize it? For example, during production we supply the machine with PCB with damaged fiducial (partially etched away, broken etc.). After it fails to detect it, is there a way to manually set it's position? I would be grateful for any help. Thanks, Martin. Tue, 18 Oct 2016 14:59:35 GMT Juki / Zevatech 740 service manual Hello. We have a problem with our Juki 740 machine. It does not start at all, both monitors are blank. The only error we can see is "FAIL" LED on CPU board and red "LD2" LED on "AC SERVO BOARD". Does anyone know what the "LD2" LED means? Or, even better, does anyone have a service manual for Juki 740 (or Zevatech 740) or similar unit. Thanks, Martin.
