We have a Samsung CP20 with window 95, S-2000 MMI version 1.27 from Manncorp Inc. that freeze on window 95 screen. It was found that the mother board was at fault & need to be replaced. We replaced it with a compatible one & kept the original hard dr

I don't see any visuals that make me think of black pad phenomena. I do note that it appears that pads on the BGA itself have detached and been left on top of some of the solder balls. To me it looks like the temperature profile is not correct, not

Do I need to lower temperature of bottom zone (for common size parts) while reflow 2nd side of the board or I should be using same profile as I used for 1st side reflow? Will parts on bottom side will stay in place without changing temperature?

I don't think you decide that based on the oven. More important is what kind of parts you have on the board. If you have big heavy parts you should run them as second side.Of course you have the option to put glue under the suspicious part and run it

I would love to use my old zevatech with a large nozzle (qfp) to pick kapton masking dots and place them on a board. I am getting some 'thicker' kapton dots to test, and need to find a way to present them, might be a trick but worth a try. Has anyon

Hi Edri, this is not a race here. Are you curing some kind of glue on your board? THe shortest profile I ever ran is for AIM solder paste - about 4 minutes total. with speed 8m/min your profile is going to be 45 seconds and I don't think this is the

I agree with AVFM. We have had at least 5 TP machines and a MY12. We stick carrier tape to scrap circuit boards with double sided tape. Teach it as a tray. Works perfect. The Count On strip feeder looks cool but is no necessary in my opinion.

Thanks for the hint. Managed to identify it easier with the codebook, it turned out to be a Phillips A6p Fast acting switching diode. Luckily I found a A6t (same but made in tiawan), tested to see if the forward current drop was the same and rework

Thanks for the info because I honestly have no darn clue about the whole industry. Does anyone know why it is expensive to have an operator? If it has conveyors can't it operate on its own? Why are the boards expensive? Why wouldn't any rigid piece

OK/NG will cost you a licence update, but it is powerfull. You can used the area color algorithm, as an alternative Black and Green have different RGB value, so it will not be mixed. You will need to tune it for a few board, set the minimum and maxim
