I have the raw gerber files used to manufacture a bare pcb. I do not have the pick-n-place file giving the locations of the surface mount parts on the pcb. Does anyone know of a software program that can take the gerber files and generate a pick-n-

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

Hi, I want to make a small setup for manufacturing PCB's based on SMD's for (pototyping boards, etc). I don't know clearly what are the equipments required for this purpose. I have an idea that we have to use (Pick n place station, Screen printing

Yes, it is important to ensure blade pressure over stencil is uniformly distributed across the entire length of blade. Such is possible only if the stencil is firmly supported from below, which during printing is done by the presence of the PCB itsel

We have successfully implemented this dual Process You can use any printer that supports Board width 500mm. SMT Dual Process Maximum PCB Width should be (500-20 / 2 ) = 240mm Max (PCB width )Printer support = 500mm Top width + Bottom width

In our industry we are producing PCB on which generally number of total component is around 2000. My query is maximum how many component or CRD we can rework in a single board, and what should be the criteria to scrap the board? Is there any specific

Yes it is possible, and yes you shouldn't trust boards that have this problem. You're best off baking PCB's this old befor reflow. This looks like barrel cracking, a quick google gives: http://www.eco3.co.uk/e3toolkit/e3toolkit/modules/05/05_04_j_pc
