I have checked the lead screw and guide rails. There is't any apparent damaged to any one of them. I was hoping it be the guide rails because they are much eaier to repalce than the lead screw. If I start messing around the lead screw, It would requi

Hi Folk, i am wondering why they are Missing ELCap and ELCap being totally shifted out of the PCB Copper Pad during the SMT Reflow. Recently we have encountered some boards with the above mentioned symptoms. Appreciate if anyone could advise me. Th

these components generally have flattened through hole leads that have been formed for SMT, I have found that they do not sit well on PCBs. They rock, the leads are sometimes angled, etc.... In addition to Robs good advice you may want to just be sur

You say you are new to SMT. If no one at your facility has SMT experience you will want to get equipment that comes with good support and excellent training. This can be difficult with used equipment. Make sure the equipment you end up selecting h

it is one of three things: 1. tape and reel done improperly from second source tape and reel op. doubt if OEM would or could do this. 2. Program is wrong in machine,or part data is bad and part is noted as nonpolarized, maybe and the machine then h

CKH, if I understand you correct, only some components(for example 2 from 10 parts in one reel) goes wrong. there is one more. How your machine alignes the components? Vision, laser or mechanicly. The problem can come from there. If the recognition

I think I read a thread very similar the other day but can't find it. If I remember correctly, the component database for that part was polarized and pre-orientation was used for camera inspection. It turned out that the optimization module in the

Hi CKH, If the problem is on the current board type only, the problem is in the fiducials or in the CAD data. If the problem remains on all boards(different product) it is definetly a machine calibration problem. Did you try to reteach the board one
