They take the solder in a dip and look solderability test but when in normal reflow process we got some pins that do not get wet and the appearance is as follows: -Pillow effect on the toe(no front fillet is formed) -There is a sheet of flux between

GerberGrab does exactly this, and it's low cost, and you can use it for a month for free. It is a sophisticated but easy to use reverse engineering tool which will automatically generate top / bottom BOMs with placement and rotation after teaching of

The 575 was based on the 570 machine. The 570 was Juki's first laser centered machine. It can do 0402 and ICs with a pitch of 0.65mm or greater. The 575, was a re-vamped 570 that Zevatech came up with. Juki played no part in the 575. Zevatech ad

We usually make a template offline to put with the assembly file. When it is time to run, place the pin support template in the machine, place your pins and your ready to go. Probably about a 15 sec setup. We looked into the ready-e-set pin suppor

Thanks to all. The way I've been doing it has been crude and very similar to your method. I make an imprint of the bottom side and cut out areas where components sit and this imprint transfers over to a cardboard. When it comes time to run the second
