yes, You need tell us how the PCB and board designed, size, material, how de-paneling the PCB?

if you can't change the PCB materials or design at this point, you might be able to reduce it somewhat through the use of fixtures or edge stiffeners. Unless it is a particularly thick board, I don't think the reflow profile would be the issue. The t

if use tray cannot solve the problem, you can change from the design 1)Reduce the effect of temperature on PCB 2) PCB USE HIGH TG 3) BOARD THICKNESS TOO THIN 4) MODIFY THE BOARD SIZE 5) Reduce the V-CUT depth.

You need to give us a little more information. 1. What is the size of your panel? 2. Are there any heavy components? 3. What is the thickness of your board panel? 4. What kind of oven are you using? 5. Is it only a recent problem or ongoing one?

Has anyone built using the ALIVH PCB (0402, 0.8mm pitch uBGA) on the SMT line? I would like to know any process issues (paste printing, p&p, reflow) related to processing this pcb. Specifically, what type of solder paste was used (no clean) and wha

Hi Dave, Immersion Ag has poor surface appearances after reflow or rather tarnished, while Immersion Tin requries higher temp. Probably that's why Immersion Ag is more preferred.

Is anyone using .062 aluminum circuit boards with copper conductors in your production lines? What kind of reflow profile is required? What special considerations are there to be looking for? I am asking for any information you can give me. Thanks

Screen printer, placement machine(s) and oven. You may also need a hand insertion line, selective solder or wave soldr and some form of electrical test. There are a ton of name brands that no two people can agree on. To get a better feel for what
