My advice for what it is worth. Your description of the problem at first glance suggests a communication problem, now is it the bus, the SMT machine or the PC. The bus could have a short or an open. The PC could have a dud controller card. or so co

Well, I have now traced the ready button all the way into the DPRAM board, and all looks good going into a big flat pack chip, valid TTL logic levels when I press the button. But, the machine will not go ready. I have no errors in the system error

| Does anyone know of an AOI system that can look at the solder joints of SMT chip devices (1206,0805 & 0603) and make a reliable presence/abscence call of the joint on a HASL PCB. A low false call rate (much less than 1%)is required. Any info. fro

You are on the right track Ismir. Essentially however, as the programmer of the machine, I am the one that creates the PCB with the errors to benchmark the settings for the machine. No secret lab though! :-) Easy enough for most any AOI machine to

I have a strange issue where all 4 spindles of head 1 on my GSM1 are able to place small parts without a problem until the very end of the routine where a large electrolytic aluminum capacitor is placed. The part is successfully picked out of the fee

I am interested to know if you solved this problem. We are experiencing something similar. The table is the first node in the CAN chain. As I see the structure, the CAN starts from the Nextmove ES card, goes first to the table driver and continues to

Just before Christmas we bought a used Fuji IP1 cheap. It took us a while but it's been working great for about a month. Yesterday the IP1 stopped after completing a board but before exiting the board out the conveyer. No error message, no alarm be

Hello Phil, AOI equipment has been around for a number of years. I remember evaluating a machine around 5 years ago. At this time the system was not able to learn right side up or upside down characters. Well, the newer systems have come a long way.

I think you could look at the phenomena in two dimensions. Many of the sub-contractors in Asia are focus on low price-less demanding products. They hire operators to visually inspect the boards and sometime there is no inspection at all. On one ha

Have you had bad experiences? We have a paste checker on line, and all components are verified at receiving and again when loaded on the machines. The purpose of AOI ( for us anyway ) is to reduce the time spent after reflow visually checking the b
