We have recently begun using X5R dielectric capacitors. Although they have a better temperature coefficient over Y5V, they age much faster (5-7% logarithmically per decade). I assume the reason for using the X5R was the availability of the capacita

Greetings, We are looking to purchase equipment to rework / repair our circuit boards with BGAs. Our newer boards are starting to have more and more BGAs. Is there any information that "ranks" BGA rework stations? - a kind of a consumer reports for

What process steps have been completed before the cross-section? What type of devices have solder cracks? Are the cracks found after just normal processing or after some type of validation testing? It is very unlikely to be a heating/cooling issue

Try a more intelligent telnet program that has a few diagnostics. I dont know the Mirae machine myself but the ext thing would be to do a trace on machine operation. maybe the booting sequence has the Telnet Host( Or is it Client?) boot after the mac

Could you make up your own adaptor cable to connect to your programmer, then fit a small form connector like a Firewire on the edge of the PCB? It should only take up about 7x7mm of real estate as opposed to a 2.54mm 5x2 pin header 12.7 x 5.08, or a

You don't mention the board surface finish, but BGA's on NiAu are prone to brittle fracture in the Sn-Ni intermetallic on the board side of the joint. You may not be able to see it visually, but it would show up in a cross-section. In-circuit test

Here's your test definitions [clipped from the dictionary in the fine SMTnet Library]: * Test, Automated. Computer controlled electrical testing of parts, assemblies, or finished products. * Test, Built-In (BIT). An electrical testing technique whi

Previously my company manufactured simple 8-10 component through hole parts. Now we have put a mixed technology line in place and are building parts with 50-100 components each. With our older units, functional test and simple visual inspection was

I�m with Stefan � no booze, drugs, or chewing tobacco in the shop!!! [I�d like to ban facial make-up, but am still limping from the last time I tried.] Stefan, how are you going to get the P&P manufacturers to agree on a common nozzle design, when
