The delamination was caused by a board falling off the rails and the operator not paying attention. I was more concerned with what fumes are produced by a smouldering board.

ah, so just for the record, it's not always the PCB fab shop causing delamination. What a nice way to end a week.

Board Experts I am fighting with a board house about a delamination problem.. First the facts 1) 10 layer board .063 thick HASL Finish Aprox 16 in x 17 in. 2) 150 Boards with this part number built with the same reflow oven settings (212 c max t

I experienced assembled boards delaminated after washed. You know...those old datecode PCBs that I was talking about a few weeks back ? I was forced to use it, and of course prior using it I've baked them. I've baked them at 125 Deg for 4 hours and/

Guys, We have experienced some delamination on 3 of 45 boards so far.(not exactly delamination yet but a gathering of moisture is evident is certain areas). We have the build on hold while we sort it out with the supplier. We are running a Leadfree

Hi, We had a electric failure on a printed wired board after a few hours of functionning. We determined that the failure was caused by a open circuit in the PCB internal layer near to a via. We performed a microsection but unfortunately, it seemes t

2) STD FR4 material with HASL finish, 4 layer board. Reflowed under tin-lead temps with another 4 layer board same time(no delamination problem). 3) We uasualy do not pre-bake board unless board is too old. 4) We do not have the board on hand right

Hi, I am new in this industrial. I learnt that PCB may absorb moisture and eventually caused delaminate after heat apply on it (reflow or wave). But I don't quite understand, if the PCB was keep in sealed bubble bag, and with the humidity control wit
