We use materials such as G10, durapol, or FR4. We put a lot of holes in the fixtures so that only enough material is left to support the board during reflow to prevent sag/ warp or whatever. We also try and keep all bot side material in unpopulated

We had a "Spring loaded" fixture that pulled the Flex tight and used loads of Board supports. There were pins that went through the Connectors holes and held the flex firm. We only had a few components so it was no problem. Lucky for us because the f

Surely this depends on the scenario? Quite a few manufacturers feeders use spring contacts http://www.harwin.com/product-search/P20-0/ perhaps a bit like these, so your PCB would simply have pads to align with those contacts. Of course this relies o

Actually, if you experience lack of witness marks, you probably have a problem. Witness marks are OK and will not affect your assembly. I assume this is an SMT assembly we are talking about, in which case, this is what your test pads are for. You

We used to use those, back in the bad old times. basically, it's a router with a blade on it that is used to trim the leads of PTH components that are mounted on boards. Nasty process. Difficult to control. Messy, firing cut leads all over the plac

Hello friends: In a few weeks we will have to assemble PC motherboards. We decided to use to purchase an ICT for testing the semi assembled boards (I mean with only SMD components on). Would anyone kindly like to recommend a SPECIFIC brand or model

Hi Folks, This is my first surface mount board, so I asked our assembly house for some tips. They said only passives on the bottom side-preferably no smaller than 0805, 0603 only if I have to. I would think that an SOT-23 would be OK on the bottom.
