You definitely need to have live demos of each system, using your specific assembly if you want to compare apples to apples. Each of the AOI OEM's you mentioned have plus amd minus to their unique systems. You will need to evaluate your specific nee

Comments are: * It�s interesting, but not surprising that your time above liquidous varies around the sides of this component. * You are correct in thinking that it is better to reduce than to increase the temperature differences around the component

Hello all, Dave, this is just another example of how your attitude towards others in the forum, outweighs your open mindedness toward their right to participate....It's SMTnet....not DAVENET. I'm not surprised to see you try to quantify the validit

Designers love to do BIG copper pours for several reasons: * Maximize heat spreading. * Increase EMI shielding. * Laziness. The poor folk that solder the parts on boards HATE big copper planes near solder pads. During soldering, fat copper traces [

Like Russ, I am also curious about the 100% fill requirement. On any thick, high mass board the key is getting as much heat as possible into the board. If you get the board to the proper temperature, solder will flow just about anywhere. As an alte

Russ, that makes sense, thanks. As for the 20x20... I was speaking with a sales rep who was trying to talk me into buying stencils from him. I told him I use "Fuji 4000" and he sent me quotes for 20x20 and 29x29. That seems odd since the Fuji 4000 st

Call it extortion if you will but it will be the best money you will spend over the life of your machine. It is nothing compared to the cost of unexpected downtime you will incur....with no support to help you out of a jam. Think about it this way.

The small shop starting with a used machine and grow larger was not the target market of the OEM, I used to work for. This may sound harsh, but the cost of selling and servicing the equipment to a small shop is comparable much higher than to the Moto

Hi Steve I understand your point, the comments on the thread of which are slightly off of the original posted question but it still is handling. Handling is handling. If you pick up a board from one conveyor just to put on another conveyor that is

Hi, I have received a report form a board supplier, analysing the reuslts form non wetting problems we have been expereincing with their boards. I assumed it was due to the gold layer being too thin, thus allowing the nicklel layer to be exposed and
