Don't forget to buy the "Lead free heelstraps, smocks, wriststraps, hairnets and repair table" too. They cost twice as much, but you have to have them! We use regular wick and it works well with the LF solder. Vendor even ageed there was no need t

If......... 1) Assuming you are panelizing them (you would have to actually).... 2) You don't have any fine pitch parts on the board then I would suggest a chipshooter like a Fuji CP-6 or a Panasonic MV2F. Get (2) of these used for around $100K ea

Take a look at Assembleon. The AX-5, similar to the older FCM, is ideal for running smaller PCB's and has one, if not the fastest IPC board speeds in the market. Something else to think about is to purchase a line. If this is an option, many equipme

I am experiencing peel back problems when a particular component is used on a Meridian 1010 and 1020P machine. I would like to start testing this force but I need some more info. Besides GPD who else makes a tester? What industry standards can I refe

I hate to ask an obvious question, but are you sure all of your thermocouples are attached properly? I just can't imagine a 3X5 board having such a large Delta T unless it has some really odd parts on it. You sound like you know what you're doing,

Yes, All six new (LF ready kit) thermocouples are tested good.I would like to say boards are populated on both side back to back with two heavy PLCC's side by side just like having heatsinks and ground plane.Some Odd design.Next try will be to have a

I can see why he left. Not knowing your board or paste, but I would tend to say your profile is on the cool side. Unless your boards are very small and your conveyor speed is slow, I'd say this is no good. It looks like you're using the old "ramp,

We are fixing to run a board with both pb and pb-free BGA's..double sided.. The board is RoHs compliant so I could go either way on the solder paste. I was thinking pb-free paste would be the best bet. Any opinions would be greatly appreciated. Th

Warp depends on: * How close the board gets to its Tg during the reflow cycle (the closer you get to the Tg the worse the warp gets) * Amount of copper on each side and the balance between the two * Thickness of the board * Overall length x width * T
