ISO Cu Wire Preservation
Nisene first saw copper bond wires almost 10 years ago. They were like a unicorn…a mythical creature created from the hysteria surrounding rapidly rising costs for gold. While the cost of gold has historically increased and decreased, the switch to copper metal bonding actually created a technological advantage, so much so that it solidified copper’s […]
Copper Wire Decap for SOT-223 Device!
Today we etched a SOT-223 device and protected the sensitive copper wires inside. Have a look! Feel free to click on the photo to view the full-size version: Wow! Even though we are using nitric and sulfuric acids, the JetEtch Pro CuProtect is quite capable of preserving the wires. Using nothing more than a very […]
BGA Decapsulation with Monolithic Gasket and Custom Backer
Today we decapsulated a BGA that was very stubborn to etch. After a few iterations of nitric-only and mixed-acid etches with nitric and sulfuric that didn\’t seem to penetrate the encapsulant, we decided to give it a shot with a higher temperature sulfuric acid etch. The JetEtch Pro rose to the occasion with an absolutely […]
Multiple Sample Etching in PlasmaEtch
Did you know that multiple samples can be processed at the same time in the Nisene PlasmaEtch? Because we have a 20x20mm effective decap zone, if multiple samples can fit in the 20x20mm one, they can all be decapped at the same time. Take for example the sample in Figure 1. This EXAR sample is […]
Effects of Excessive Ultrasonic Processing
It has long been an industry practice of post-decap cleaning an integrated circuit via ultrasonic. This process is done for multiple reasons. Decapsulation done through wet-chemical processing, like the JetEtch, can result in residue on the surface of the die and bond wires. While this residue doesn’t necessarily need to be removed, it can inhibit visual inspection. It is […]
Accelerated Plasma Decap with CF4
The Nisene PlasmaEtch was specifically designed to include the use of CF4 gas for many reasons. One of those reasons is CF4’s ability to break-up silica in mold compound. By allowing a plasma process to incorporate CF4, an end user has more flexibility to adjust their recipe when a mold compound has a higher silica count […]
