How to remove IC part number?
Using a Dremel tool to remove the part number, logo, and additional markings from an IC. Hiding such markings is commonly used as a “security through obscurity” technique in an attempt to make device reverse engineering more difficult.
How do you identify the PIN numbers on an IC package?
The pins are numbered anti-clockwise around the IC (chip) starting near the notch or dot. The diagrams show the numbering for 8-pin and 14-pin ICs, but the principle is the same for all sizes.
How do you make Decap chips?
There are a few different ways to decap a chip, but the most common method utilizes chemicals like nitric acid, sulfuric acid, and acetone to essentially melt the epoxy right off the top of the chip, then neutralize the acid so it’s safe to examine.
How can I open IC file?
Follow These Easy Steps to Open IC Files
- Step 1: Double-Click the File. Before you try any other ways to open IC files, start by double-clicking the file icon.
- Step 2: Choose the Right Program.
- Step 3: Figure Out the File Type.
- Step 4: Check with the Software Developer.
- Step 5: Download a Universal File Viewer.
What is a DeCAP?
The Dependent Care Assistance Program (DeCAP) is a way to pay for dependent care expenses with before-tax dollars. By enrolling in DeCAP, you not only plan for anticipated dependent care expenses but also reduce your gross income for federal and Social Security tax purposes.
What is COB IC?
Chip on board (COB) is a method of circuit board manufacturing in which the integrated circuits (e.g. microprocessors) are wired, bonded directly to a printed circuit board, and covered by a blob of epoxy.
How can I remove the labels from ICS?
One suggestion was that IC manufacturers are often willing to put custom labels on their chips. The idea is interesting, but my quantities are low enough that this would not be cost-effective. How might one remove or otherwise render unreadable the labels on ICs? Grinding or other abrasives is the only reliable method.
Can you change the markings on a laser chip?
If you have large enough quantities, you can request them to change the markings on the chip. (but as you said your quantity is too low). The bottom line is, if you have any fairly large quantities, the laser still remains the way to go.
Where are the supply pin locations on an IC?
The supply pin locations are one giveaway, and the rest of the circuit (unless it’s really novel) give a pretty clear indication to an experienced observer. On the other hand, you just need to make it more of a pain to reverse-engineer than to redesign from scratch. Google the phrase “ic remarking” to find many suppliers of this service.
