| I am experiencing a problem with a surface mount coax connector that over time pulls loose from the PWB. The connector has 4 small gold plated leads and we are soldering it to a flash gold board. A cable plugs into the connector and puts some con

When you say, "you can see the plating of each lead embedded in the broken solder joint", we do not get the sense of a well soldered connection. * We don't expect to see [or make the distinction] of the plating from the connector in the solder. We

Samir, This growth doesn't look like a tin whisker which are needle like and very fragile (they don�t bend they break). I have seen similar growth in the past in an EMS defect analyses with connectors in stressed conditions. The growth seen was sim

Wendy, I've done this before using a machined piece of FR4 material to hold the board (machined like a DEK plate )in place at the press . It ensures that the boards are alway's in the right place and that none of the components are damaged..also sto

Steve, I onlyworked on the soft beam for a few months. With a good operator it ran good. The biggest problem i saw was the solder would break. The operators would try adjusting and end up moving the solder point. We had two machine back to back one r

Keep in mind that device pitch, pad geometry, lead length and even alloy type will play a roll in your evaluation. I have an assembly that we run 10k pieces per month. One two-pin connector has a pitch of 1.27mm. Unfortunately, the pads are 0.007"

The Philips Orion (Yamaha YV100) Head I/O Board is usually at fault as this tends to suffer trackwork problems with age due to the constant flexing of the board stressing the connectors on the board, thus breaking tracks within layers. You should not

Well it rarely fails that I post here and resolve the problem shortly after. I noticed the "PelSizeY" value was in the hundreds instead (188) of tenths (0.155) which indicated some issue with Y calibration. This coincided with the alignment issue-
