Start with targets based on the stencil thickness (for height) and stencil thickness times the aperture size (for volume). * Set reasonable upper and lower control limits (+ 25% and –25 % of the targets, for example). * Next, check the printer set-u

It is a little bit sad that I know this - be prepared for some confusision - this is not as simple as it might seem. Something tells me that the calculation of the tolerances for the nominal dimensions is a little inconsistent. As I recall the defa

This is interesting Alexei. So Flex is able to check my complete project before I decide to start manufacturing process, and advice me what should I change to minimize quality and assembly issues? I'm really interested in finding such service. Do the

Hello all, our company is having issues with boards that are coming in warped. According to IPC-TM-650 it is said that one should use a flat plate when determining acceptability of warpage. What I would like to know is: 1) What should we be using

Well John here is the situation: I need to place an infrared transistor (optical element) with a tolerance of +/-.003", this is not a problem. A lens is positioned over the optical element and snapped to the PCB via three holes that have a toleran

The must-do is to inspect for coverage and registration. How much bare pad and registration error you can tolerate is process and product dependant, but you can measure both fairly accurately with a reticle on a microscope. Developing measurement te

We are currently using Oven Rider (ECD) to "verify" just the conduct of the peak temperature; we define which product is the higher runner for this line and then with the settings for this product (already profiled with thermal couples attached to th
