Thank you! I am looking into this, but main idea is to use rigid board in place of flex.

I would recommend that you turn toward your PCB supplier probably China and talk to them. You should always bake your boards if this occurs. If you purchase them form a trusted source you should store them in a McDry until you use them if possible. I

Has anyone ever used local fids on flex circuits that are applied by the board house as black ink dots? Good or bad experience? We have a flex board that has two identical 60 pin, fine pitch connectors on it. From limited experience and reading so

OK, I have a new product being tossed over "the wall" that has a flex circuit layered into a standard FR board and protrudes out of it. The flex circuit is 0.022" thick and is the 3rd layer of 6 layers. The total board thickness of the FR board is

I am wondering if the failurs that people see are discovered right away or when the units are out in the field. Reason I ask this follow up question is the units that are having problems are all returns from our customers. Is there a way to check for

Ron, The simplest way to process fexible PCB's that I have found is to use a process carrier fixture. There are companies that manufacture process carriers that are capable of holding flex through stencil, placement and reflow. The carriers are capab

AccuFlex is the replacement for UltraPrint 1500. UP1500 is going obsolete. AccuFlex was desgigned for fast setup and changeovers and takes some tasks away from the operator. The UltraPrint 2000 was designed for high production, even though many users

Hi Dave, This is manufacturer applied epoxy / adhesive to minimize package "lifing" from chassis flexing and thius board flexing. I have seen the complete array area covered with this black or red epoxy in some cases (i.e. the underfill that I've

We are doing what I believe is unique from everyone else. We are using a .010 thick flex circuit board populated with the usual components, sot-23, caps, resistors,etc. It is mountd to a carrier plate with the edges taped down but I am having troubl

Hi, I am having a problem with component position on a flex circuit. It is an eight up panel. The flex circuit is mounted on to a piece of fr4 with presure sensitive adhiesive, this is done out of house. The problem is, I will locate the parts on one
