I am having issues with a CS-400E that I thought I might ask if anyone has any suggestions. The machine may run fine for a while then out of the blue the cutters stop responding or start responding erratically, you have to hit the esc key after ever

The 400E has a computer on the bottom of the cabinet with a a Serial/Keyboard Card installed in it. J1 pins 19/20 are the cutters transmit/receive lines on this card, they go through a transition brd and on to the Cutter/Processor brd on the side do

Thanks Dave...it's such a good site for reworking BGA's (reballing). But what about when it comes to re-attaching the BGA onto the PCB? We are using Flextac Stencils but I found out that the apertures of their stencil is bigger than our pads for the

When it comes to re-attaching the BGA onto the PCB, we don't those very nice mini-stencils. They are very nice though. On sources for your rework stencils, try your stencil fabricator will be happy to make those very nice things for you. What's wr

the ones we use have a temp adjust/control. To answer reflowing adjacent components we reflow them during the rework. However if we do not want to reflow we either change the tip on the gun to a more localized area or we apply temporary mask to pre

Jon, one other option. Metcal makes tips for the MX stations that are for removing All sorts of Ic components. They are custom sized for each QFP size. If you have the MX stations this is a great way to go. These tips only heat the leads and par

Hi Daniele: In a design of experiments with four methods for attaching thermocouples : High Temperature Solder, Aluminum Tape (Chomerics T405), Kapton Tape and Conductive Epoxy (Loctite Tak Pak 382. The most reliable method is high temperature solde

If this is a requrement from your customer then: They should supply the name/brand of the material, AND they must supply solder samples because their requiremnt is a destructive profiling technique. You should charge them more dollars for setup and

Steve is right, Cyberoptics and ASC are the 2 main players in this market. I've used machines produced by both manufacturers and they both do a pretty good jod provided the operators know what they're doing. The LSM and LSM2 are solid but aging mac

I'm hit with the above problem and found out that the BGA's themselves have fibres on their solder balls. I have soldered some without having the knowledge of the above fibres and found that the fibres are caught between the PCB pad and the BGA solde
