Some Customers normally don't share CAD data in order not to copy the design. What you can do is use the Pick and Place file then plot to the pcb paste/silkscreen layer of the gerber using software. Not sure if your universal machine can load a gerb

Hi Wnb_Pemgr, I am not sure where your facility is based but I was hoping that we might be able to help with some of your issues? Hopefully we can support you with any ongoing problems you have or escalate any cases you have already made with Koh Yo

I have seen similar things happen with over etching and bridging but frankly the most common mistake that gives us grief is a failure to use the component manufacturer's recommended land pattern and/or aperture designs. As opposed to generating a n

You are asking a very good question which has been an issue in the industry for a long long time. For operating at 225C, you will need a solder with melting point no lower than 270 or even 280C. HMP solder is very difficult to come by. At this stage,

Thanks for that info... I found out that MPM has UP2000 HiE VP with price lower than DEK Horizon but just a bit higher or let's say relatively the same as DEK ELA...I find it hard to decide which among the 2 based on our budget capability. My budget

If you are talking actual placement rate- from first fiducial read of board no. 1 to first fiducial read of board no. 2, here is the best I've ever seen based on the boards I've run: CP3- 141 seconds for 468 components per board (all rectangular chi

Hi Christina, What would you be basing the yields off of? Is it solder defect, component placement, etc....? I have worked for a flex house for quite a few years. You are right. The Polyimide is very dimentionally unstable. (even more so on humid da
