That is very interesting... I am curious though, why wasn't a plain blind rivet used? You probably can, but personally, I would be not want a solder joint holding the frame and the pcb... Mechanical stress on solder joints often leads to not good re

I'm not sure this would solve your problem but Inovaxe has done a good job of solving MSD and inventory handling and control. They are also a sponsor of SMTnet...here is their SMTnet listing followed by thier web site for their carts... http://www.sm

Can anyone help me recommend or simulate a SPI and AOI machine that can balance our FUJI NXT 1 with 14 modules. We are using MPM accela printer. 200 UPH is our target. Here's the PCB dimension length(x) = 399.92mm width(y) = 141.626mm Thanks all!

Hi folks, thanks for all the tips. We have run our first batch of these flexi boards now. I had the PCB suppliers make me some 1.6mm FR4 carriers to lay the boards on to carry them through the process. (1 flat & 1 with cutouts for the second side)

that's a pretty cool idea, I like some thinking 'outside the box '! 1. I don't think picking it up and placing it will be much of a problem. once the rivet is placed it will be held in place by the paste. However, you would need to make a tray that

One important thing to look at, when buying an AOI is the False Calls Rate, along with tact time of machine to inspect the PCB. Obviously, many machines can do the the work....but it's also true that each machine differ from the way it do the work. S

Russ, We can not use a wave pallet, already went that route. We have parts next to the thru-hole pins and between thru-hole pins. I am going to try an experiment in the next day or so with solder mask. I plan to solder SMT parts on the back of se

Yep, Book a holiday and let someone else sort it out. Otherwise e-mail me and I'll talk you through pallets, rigidisers, printer tooling, spray mount, Kapton tape, local fiducials (panels can strech & shrink) etc. Oh, yeah - for the connectors you

Any decent flux would volatise off with the heat of the wave unless absorbed into the solder mask. Test this by trying to clean in alcohol or common solvent aerosol, if it does not clean then it is probably Mineral Salts from solder mask fillers. Ano

Occasionally solder mask thickness is believed to be the cause of gasketing challenges during paste printing. We currently specific IPC-SM-840 on our fab drawings but this provides no limits or guidelines on thickness. I do not want to cause an unr
