Hi CKH, Here's some things to consider: 1) Moved by obstruction in/entering oven, such as nitrogen skirts 2) Incorrect air pressure/air leak in oven (large surface area on component) 3) Reflow temperature too hot & electrolyte/air in cap is expandi

We are constantly messing around with easy ways to transport double sided boards through reflow. (Boards that cannot ride on the chain fingers for any number of reasons). We've got some fancy Durostone carriers that work awesome but are product spe

A little more detail on our application: It is a large fixture (approx. 15" x 18") that spans the chain fingers in the reflow. It has several cut-outs and reductions in thickness to allow for better heat distribution. It worked well/stayed flat fo

We've never, to my knowledge, sent out Pb-free BGAs to be reballed for use on an SnPb assembly. In fact, we developed an in-house reballing process and we haven't felt the need to do that either (for salvaging an occasional reworked part, maybe).

Thanks Jeff, I isolated the problem to the DC servo part. The GD3 signal in the safety circuit chain is the one that generates this L004 Feedback Error - which by the way next to it I get also (Wn) where n is changing form 1 to 3 every time I push r
