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

R series Features FCS (Flex Calibration System) highly regarded easy maintenance just got even easier! The optional FCS calibration jig is a simple to use system to re-calibrate placement accuracy. The machine automatically picks and places jig comp

We've had much trouble with flex circuits. As previously mentioned, you must have local fids for the board or the BGA itself (if panelized). Other troubles we experience are drilled holes for pinned connectors. Unless the PCB manufactur has some w

we have both flexjet and flexhead, we also have the new inline 7 head on some genesis dual beams we just put into operation. If you have a choice in flexjet heads take the inline 7. The flexjet 09 head is very labor intensive, stay away from them, e

Hey Dougie, If you go to IPC.ORG and click on the on-line resources and databases, then on the "free downloads" link, the second or third document "for free" is the IPC-TM-650 in its entirety. It does discuss the test you are looking for! Have fun

Dear Friends, I need your help to understand requirements and measurement methods for bow and twist of assembled PCB (PCBA have and SMT and TH components). I already check all posts on the site but didn't found any related to my question answers.

Dougie, oh yes, it�s a bit short that chapter. I have the Revision e in front of me and this one contains in the appendix the needed IPC-TM-650 Test method for bow and twist. Can�t think that they don�t have that in the new revision. Hope you find

Dougie- We,too, have the IPC-A-600F, and the spec. refers to IPC-TM-650 test method in the back of the book. Look on page Number 2.4.22 of the test methods appendix. This outlines the procedure for determining the percentage of bow and twist,

Is there anyone who knows the yield rate difference for SMT on multi-flex boards and rig-flex boards ? Basically, I think the yield rate should be higher for rig-flex than multi-flex due to the poor dimensional stability of polyimide, since multi-fle
