Get Down to the Die Level with this Internal Chip Repair

Usually, repairing a device entails replacing a defective IC with a new one. But if you’ve got young eyes and haven’t had caffeine in a week, you can also repair a defective chip package rather than replace it.

There’s no description of the incident that resulted in the pins of the QFP chip being ablated, but it looks like a physical insult like a tool dropped on the pins. [rasminoj]’s repair consisted of carefully grinding away the epoxy cap to expose the internal traces leading away from the die and soldering a flexible cable with the same pitch between the …read more

CES2017: Complete Register Documentation For The C.H.I.P.

Last October, Next Thing Co., makers of the popular C.H.I.P. platform unleashed the C.H.I.P. Pro, a very capable Linux system on a tiny board. The goal of the C.H.I.P. Pro is to be the brains of a project or product, similar to the Gumstix boards from an ancient era long before the Raspberry Pi.

Introduced alongside the C.H.I.P. Pro was a fantastic little device. The GR8 module is a complete Linux system on a chip, with an ARM Cortex-A8 processor and 256 MB of RAM, all on a relatively small BGA chip. This is a drop-in part that gives any …read more

Ken Shirriff Takes Us Inside the IC, For Fun

[Ken Shirriff] has seen the insides of more integrated circuits than most people have seen bellybuttons. (This is an exaggeration.) But the point is, where we see a crazy jumble of circuitry, [Ken] sees a riddle to be solved, and he’s got a method that guides him through the madness.

In his talk at the 2016 Hackaday SuperConference, [Ken] stepped the audience through a number of famous chips, showing how he approaches them and how you could do the same if you wanted to, or needed to. Reading an IC from a photo is not for the faint of heart, …read more
