Steve, I have no influence over conn design. We paste print-reflow solder two types of connectors. One is a 50 pin IDC w/ 0.5mm lead dia @ 2.54mm lead pitch and a chamfered pointed lead tip. The other is 32 pin DIP w/ 0.36mm lead dia @ 2.54mm pitch

Pete, I'm wondering how much optimisation you needed (or were allowed) to do with respect to connector design. The first one we evaluated had a row of leads that I can only describe as "crescent" shaped in cross section. Impossible to get even 50%

I'm attempting to develop paste in hole process so that I can reflow a few plated through hole components on a mixed tech board. Tried various pastes, profiles and stencil thicknesses. Would appreciate any insights and/or pointers anyone can share on

Hello friends , in order to try to reduce our labour cost , we are thinking to replace manual placementof PTH COMPONENTS by automatic unit which 'll be able to place relays ,and connectors . is there anybody on this forum to advise us on this topi

I need some input on what good solder thieves dimensions should be. I am limited to solving my bridging problem with solder thieves; all process/wave variables have been adjusted to try to solve this problem. There are several of these connectors on

If by the Powers Ta Be (customer/designer), you can't change the PCB design, negotiate for the PCB fab house, to block the via holes with their (green?) solder mask some customers/designers want to have via holes to be present in the PCB pad, due to

Hi "some customers/designers want to have via holes to be present in the PCB pad, due to some belief that it helps in heat dissipation. " As I think about this I don't know exactly why they would be concerned. I can imagine in some exotic products

Iman On your situation: As an earlier poster stated, your options are limited to opening you stencil aperture to compensate for the paste lost to the via. On your designer's belief that "it helps in heat dissipation": Could be true, but: * Hole wil
