Integrated Circuit (IC) devices are packaged in black boxes to protect the chip from the environment and to provide a standard outline for Printed Circuit Board (PCB) design and automatic pick and place. Chip, supporting leadframe and interconnection components are encapsulated inside the IC package. Epoxy molding compound is the most widely used material for IC encapsulation due to the low cost and good performance.
IC failure analysis may require looking into chips, wires, and devices that do not allow for observation of their internal parts because of their external package covering (Epoxy). The external layers blocking observation may be removed by proprietary techniques (chemical) etching to uncover the devices packaged inside for further treatment and observation during testing.
Decaping is the process of removing the black packaging material, which makes up a microchip in order to expose the silicon chip inside. The silicon chip inside is where all of the processing happens and is where the data is stored. In the case of a microcontroller, the kind you would find in most electronic devices, it is also where the firmware is stored.
In silicon chip, many secrets of integrated circuits are hidden, an analyst looking to uncover a failure. One has to extract silicon die and each layer has to be captured during the process to figure out failures. For microprocessors, there can be a different metal routing layers. Capturing of images can be done using normal optical microscopes to sophisticated instruments like SEM / TEM.

Left us a star review
A very good lab delivering acurate results. I must also mention about the very cordial staff that they have.
Great work done by nishka research. Thank you so much for your kind Co operation
Thank you for your services.. Looking forward for more collaboration with your labs for my future projects..
Submitted the samples for my phd work . Great work and reports submited with 2 days of time . Also the image clarity and all data are clear .
I am a PhD scholar from Kaunas University at Lithuania, Europe. I have given a sample to perform SEM analysis of the organic tissue. The results are highly satisfactory and impressive. The service was really excellent, on time( even before the time schedule), consumer friendly. cost to the academic samples are very less comparing with others. Once again thanks to Nishka for providing me the service ontime as I am really in urgency...
