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

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

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

Hi, Does anybody know where I could get a cheap but efficient press for press fit connectors (200pins and up)? Pneumatic or Hand lever Mario

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

=130�C as per IPC-4104/21 What will happen if I expose the PWB Assembly with components to a temperature of between 135'C to 152'C, which is above Tg, for 1 hour? Will there be delamination or possible damage to my PWB? What about with the rests of

Ron, We use 100 pin straddle mount connectors on some of our 1.6mm boards (up to eight per board.) They come to us from the vendor with a bead of solder on the somewhat 'J' shaped leads. Our process is as follows: Mount connector to board with hard
