What kind of equipment do you have now to do the 1 off boards? Is there enough profit margin to process the 200 the same way? If not, there is not enough to justify new equipment and to outsource 200 pcs with 100% traceability requirements would

Requesting help from anyone with experience in reflowing Te Connect, PN 1565917-4, 200 pin connecter. Pic attached. Cannot get all 200 pins to wet, main suspect is slight PCB warping during reflow. Have adjusted reflow profile. A 2.75 inch long SMT c

We place these on a few boards and have no issues with reflow or warpage. How thick is your PCB?

The connector is so long, and has big metal parts, it will be little deformed during reflow I guess, andthe pins planarity should be critical for 200 pins. Did you measure the non wetting pins profile to see if temperature ok? And maybe you can try u

Help! We currently use out SMT for pretty much one-off's. we use BGA's and complex board designs and it looks good to say it's been SMT'd. We are now looking to take on a project (a one off project) that would move our production up from 1 to about 2

You can try putting titanium stiffeners on the PCB to prevent it from warping. How thick is your stencil? More paste would give you a wider window however too much and you risk bridging. You could try over printing the pad at the heel and toe to get

Appreciate the input from everyone. The PCB is .062" thick. As a CM we are at the mercy of our customer at this point although (hopefully) they are receptive to advice on the next build. Titanium strips could be an option, I also thought there might

What solder alloy are you using at the moment which is coming to the end of its limits ? Normally in general for safe operation of an alloy we don't like to recommend any operation temp that is higher then two thirds of the solders melt point, but th
