The NexLev connector is built in a stripline construction, providing a continuous ground plane for each signal contact. The connectors come as tenrow connectors with 100, 200, or 300 positions at possible stacking heights from 10 mm to 30 mm. Technic

SWAG is prolly right. You can verify the tactile sensor by watching the machine carefully. When finding the stencil height, make sure the board goes all the way up and touches the stencil to trigger the tactile. If it doesn't, then something is wr

One printer 2 smt lines = No problem, but then you will need 2 ovens. It is even sometimes a more valuable cost savings depending on what production you are into. At first the stencil printer with a divertion conveyor, then straight ahead into the 1

Acquire a fast dispensing machine that can deposit solder paste to keep a low volume pick and place machine working. This would save us two things: 1) Stencil delivery waiting period for customers who bring with them their PCBs fabricated in the loca

Search the fine SMTnet Archives for previous discussion. This technique has been called 'pin-in-paste,' 'paste-in-hole,' 'intrusive reflow,' 'alternative assembly and reflow technology' and who can remember all the other consultant buzz-words. Look a

Greetings everyone. We are currently doing some experimentation with solder paste printing over ground planes. In this application, the entire perimeter of the PCB is a ground plane. It's about 4mm wide and wraps around the whole PCB; There is no so

Loco [snip] "The print mode is another consideration. Printers are designed with a squeegee bar and a flood bar. In flood mode the flood bar spreads the paste, and in print mode the squeegee applies pressure, such that the actual printing takes plac

Franx: In response to your follow-up questions ... For the case 1: Q1: Should I apply the glue to the PCB with the same method as I apply solder paste? (with screen printer and squeegee). A1: Correct. Glue can be stencil printed, dispensed, or pin t
