Mark, A challenge for sure. I suggest you review two techniques for this type of rework\modification. The first method uses a special circuit track run out from under the BGA. See: Jumper Wires, BGA Components, Circuit, Track Method at http://www

| Thanks Dave, | | But still I have the following question unanswered, in a technical point of view: | Has it sense to measure this on A system like we have now, because there are no wires that can be broken. | George: While I agree that no wires c

Try this: * Lay the board onto a solder pot with the via in question on the heat. * Push the wire into the via. * Step back and pat yourself on the back. Since you probably have components in the area of the via that you don't want to cook, try a va

Hi Wow, Sounds like a neat problem. As an other idea try inserting the largest wire you can get in the hole and heating the free end to wick solder up the wire away from the hole. I probably like the solder pot with a small nozzle the best so it h

We are currently producing a board for a customer that has about 400 gold fingers that get wire bonded after the assy. leaves our facility. We have tried many different approaches to ensure that we are not getting solder on the gold fingers. Nothing

If it is a MPM printer you can install the environmental control unit. But it isn't as simple as most people thinks. You also have to install a thermostat inside the machine. Then there is a wire that is used to turn it on and off, this wire is fr

We've recently encountered some problems with wire bond strengths. I'm looking for anybody that has had some experience with different types of substrate contamination and methods for cleaning. There is no visible contamination on the gold pads, bu

We have some no sticks, but that is actually a good thing because we have NSD. During process control audits we found that pull strengths to the board dropped off. We build a military application that requires higher bond strenghts. Low pull streg

Todd, It's been a while since I have looked at this but I believe the IP-1 does not have a relay board for the feeders. +24 Vdc is wired to a pin on the connector and the I/O board (NO 3 I think) switches the ground. If you don't have +24 Vdc at 1
