We are looking at reflow soldering some Flexi-rigid pcbs. I have heard that IR reflow soldering can make the Polyimide "self heat" and cause de-lamination. Does anyone have any info.

Has anyone built using the ALIVH PCB (0402, 0.8mm pitch uBGA) on the SMT line? I would like to know any process issues (paste printing, p&p, reflow) related to processing this pcb. Specifically, what type of solder paste was used (no clean) and wha

use a solder join temperature of 200/210� whatever the pcb used (tin lead coated or osp or gold fash). 2nd ==> to adapt the temerature to the pcb used: - Reflow (200-210�) for tin lead coated pcb's (in this case we have just to reflow the solder

My guess is that he is talking about the gold plated pads not fully wetting with solder. We have seen this on some of our ENIG boards with the gold still showing at the far corners of the rectangular pads. Not knowing if this is hand soldering or p

Screen printer, placement machine(s) and oven. You may also need a hand insertion line, selective solder or wave soldr and some form of electrical test. There are a ton of name brands that no two people can agree on. To get a better feel for what

Good afternoon, Take my word, bent THT leads will surely cause problems with manual/automatic component insertion, and surely will create voids in solder joints. As a rule, PIH components are placed by hand and good PIH THT manual component placemen

OK i have a question: I have a prototype BOM and i suggested the customer that we use Paste-in-hole for the 1 connector that they want to use, but its quite high component and not very wide: http://www.molex.com/pdm_docs/sd/022272051_sd.pdf If i u

U might need to run the board on a reflow pallet with a clamper. This will help to solve the warpage problem on the PCB and connector.

Good Morning WS, If you experieced the solder balls after reflow of a bare board through the oven, then the source of the solder is either the oven or the board. I have had boards with untented via's that were HASL'd that had entrapped solder and fl
