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

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?

Hi anyone knows what is the minimum copper foil thickness available across the industries to make PCB surface. Intention is to achieve 23 microns of finished copper thickness in a 0.3mm thickness PCB. Ideally if 3 microns plates are available, additi

Anyone know what the general rules / requirements are for micro-BGA's and CSP's as to when capillary underfill is required? (ie size of bump/ball, package thickness, PCB/CSP thickness ratios, etc).

oh i did not enter the pcb thickness. it is set to 0.0 I thought this was only to be changed for non standard pcb thicknesses. So, with the pcb being 1.6mm this is probably the answer. I guess this means I'm dumb..

I have a problem recently to qualify QFN package on solder joint reliability. The pcb thickness stated in IPC-9701 is 2.35mm but from the in-house test, QFN surface mount on 2.35mm thickness PCB board have a short cycle to failure due to higher CTE m

There are one value for thickness during PCB-teach function which is the PCB thickness. The other one is the camera focus in machine option but it is a dangerous function because the camera focus is adjusted by raising/lowering table.

I had a similar situation with a very thick PCB (0.23") I could not get a TAL lower than 160 sec, I've spoken with my paste supplier about this issue and we have made some adjustments on the oven and we could lower it to 145 sec, I know it is higher

The general guideline for most PCB manufacturers for PCB thickness tolerance is +/- 10%. Is this documented in an IPC spec? If so which one? Thanks Dave

When do we need to implement a pallet for a PCB during SMT process?Any recommendation on PCB thickness,panelized PCB,width and length etc?
