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

It is possible with a few universal profiles. I did this with 3 temperature ranges and 3 speeds for each, 9 profiles total. With this setup I could run any of about 150 boards most of them in the middle 3 profiles. My goal was to reduce change over i

It�s sometimes tough to put enough paste on the board before reflow to obtain half-way adequate hole fill with components on a 0.062 inch thick board. So, a 0.093 incher, um. Yano, a lot is determined by board lay-out and how you jigger your profil
