We recently had a multi block panal change at the vendor Now the production lines are producing solderability defects in great number. The makeup of the pcb is a type of fiber glass mask green in color and pads with no tinning just copper lands.

Hello, I need an advice regarding the next issue: in the case of Assembleon Topaz or Emerald SMT machines, is there necessary to teach first the block repeat coordinates and after that the PCB fiducial coordinates when you do not have these coordina

this is the order that I use. 1. Teach pcb origin 2. Teach fiducial location 3. dial in vision on fid in mark info. 4. go into mount and verify that the primary image is on in x/y (after perfoming a teach trace condition) and then do any offsetts if

I am looking for advice on sourcing a x,y digitizer to create pick and place files, off-line, rather than programming with the machine. I could use original gerber data or create the placement coordinates with the digitizer. Also, references to equip

CIM systems for electronics assembly have traditionally considered the PCB only. Final assembly "modules" are often attached to traditional systems to accommodate this common requirement for pre-PCB assembly, mechanical assembly, and final assembly

I'm planning to design the pcb of my project. The controller used is having 136 pins and the package is P-LFBGA. So i think i need to design a 6 layer board for better performance. I haven't designed a multi layer board before. So what are things tak

Hi Mikey, Your signal pins (2 & 3) for USB1, 2, & 3 are all connected together so there is no way of splitting the incoming signals from the 3 ports. Normally there would be an IC (a USB hub controller) switching between the signals so that the PC

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
