Hi Again, As I was thinking about this, I remembered another unconventional way that I was told about from one of the starters of this technology. Now I don't think anyone would use this technique anymore, yet here it is: Press Cutting and Pushing

Typically 1% resistors indicate the decimal position with an "R" 22R1 most likely means 22.1 ohm. Again the best answer is to go to the manufacturer's website to learn how to properly identify the particular component. The ones that really confuse

Does anyone have a tried-and-true method to account for machine losses of SMT parts? I remember reading an article once that stated that 5% - 10% of components of certain sizes are known to be lost during placement, and I know some CM's overplan by 5

Are there any equipment manufacturers that provide this option? I have a potential customer who has stated the other CM's he has looked at has this option on their equipment. I have never heard of an optical comparator built into a pick and place mac

Hi I think you already have the answer. It isn't the same as the true comparator of yesteryear, yet YES, some of the assembly machines have visualization post placement, compared to a golden board or dimensional images imported into the software.

Hi There: We have a wavesolder m/c with foam fluxer. I want to know: - When we do not run the machine, how to keep the fluxer porous cylinder in a good condition? knowing that we use no-clean flux. Is it the same when we stop for a few days or wee

Haran: Have you made improvements regarding your BGA shorts? We are facing the same problem and we think it is partly because the non coplanarity of the seating plane of the BGA which causes BGA balls to squeeze on one side of the BGA. Also, we ha

Arturo, So, you're not shorting to a thermal pad. Given that you're shorting to outer balls, tell us about: * Location of the shorting among the outer balls. * Board construction. * BGA constuction. * Paste deposition. * Temperature measurements ta

Our new Site in India has been running a lot of NPI lately. Most of the operations, is done manually i.e. Manual Insert. I was asked by the Development Group to invest on AI machine. I'm not sure of whether I should proceed with the investment or no
