How high are we talking? 1000 Celsius? KIC Thermal Profiling double sided aluminum profiling tape. I have used at an extreme application of 240 to 300 degrees celsius for 18 minutes. With up to 30 passes with no visible degree of deterioration.

Hi David, we used the following techniques in high volume production, depending on the type of flexi-board: (all were in milled pockets in a durastone pallet) 1) Kapton tape top & bottom 2) Spray mount & samll amount of kapton tape (you only had

On any new project we use double sided tape and place all the components to check for placement accuracy and polarity prior to pasting a board. We salvage any large/high dollar parts and toss the passives.

To me the most challenge would be the printing step. If you can print it, you should able to run it with SMT. We ran similar thickness flex boards before. But it's long flex with small stiffener at both ends, and it was 10up array. You need fixture

I have to agree with Steve. If the problem is progessively worse the problem is the pitch conversion that was used, and I have seen it before. It may be masked by the solder paste which could be on pitch but after reflow the paste wickes to the pad

Hi mates, need some help to resolve a thumb-twine situation. As a high-mix, low volume prototype build house, we always conduct a first article inspection (FAI) on every model setup conversion in the SMT production Lot run. we do this FAI by mounti

Hi SMT Frog We are using an upgraded Mydata TP9-1 system to place 0402s. We do an electrical test plus mechanical centering and use the C14 tool. A few things we have observed/learned: 1) Is the machine not picking the part up out of the tape? Po

You may care to review the following from my Circuits Assembly page on line. "HOW FLAT IS FLAT AND DO WE NEED FLAT CIRCUIT BOARD, YES WE DO ? As production problems go there is one that keeps reoccurring time and time again. The blame is usually di
