We have been pretty successful with screen printing glue, however the smallest component we now glue is a 0805. We had many problems using our Gemini II to put down glue dots for a 0603, so we altered the pads to do double-side reflow. As our own int

Go inform the owner of your company that you are spending hours of labor dealing with these parts instead of spending the extra 4 dollars it takes to buy an entire reel. When we deal with strips we make sure that an extra amount is ordered to apply

HI John, I use wave fixtures with titanium inserts. So far I have not seen any problem with walls about 0.010" thickness and 0.120" tall (or deep depending how you see it)...The Titanium-composite interface is also very strong (as long as you have e

We are increasingly being asked to store components for longer and longer periods which we know through experience leads to reduction or total loss of solderability of the parts. 1) What is the industry accepted shelf life of tin/lead plated compone

Hello Paul, Without all of the specific details of your product I would recommend providing the BOMs and samples to a couple of vendors and have them prove their capabilities. The Siplace platform is a solid platform for your application and the ap

A laser cut stainless steel stencil was used exclusively for the evaluation of the complete 0201 assembly process, which addressed printing, placement, and reflow. However, I have also conducted off-line 0201 print tests using a nickel electroformed
