Hi Experts, If SMT Type DDR DIMM Socket , PTH Pin size:2.5mm , PCB hole 2.45mm, Could this design can use placement machine to put DIMM on PCB? How to overcome the interference between PTH pin and PCB hole? Thank you Best regards James

Just curious if anyone else has trouble with the installation and inspection of DIMM Connectors (I know - these are through-hole parts!) We have boards with 240 pin DIMM connectors and occasionally a pin may not be properly aligned prior to press-f

Do you of reducing hole size of DIMM connector will improve solder voids??

All, We are having insufficient hole fill only at DIMM connector area(120 pin/row total two or 4 rows at that area) when we switch to lead free (SAC and Sn/Cu). The finish we using is immersion silver. Preheat on top side ~98-118oC. Rosin flux type.

first of all, you need check the strain caused by interference during connector insertion. If must done by SMT, then a claw would be better than nozzle.

Hello all! Recently we got a problem about the Funtional test. Some boards passed tests by using the auto-fixture(vacuum), but failed by using manual test fixture(need to plug CPU, DIMM etc.). The error symptom is no picture. We doubt it's the proble
