How To Open The Encapsulated Chip?

The sealing chips generally include:

1. Chip, this part is encapsulated and protected, and can only be seen after Kaifeng chip.

2. Shells usually use epoxy resin, ceramics or metal materials as cases. The shell protects the internal chips from physical damage and environmental factors.

3, pin, one end of these pins is connected to the PAD of the chip, and the other end is extended to the outside of the packaging to install it on the circuit board.Through these metal pins, the chip can pass the electrical signal with the external circuit.

Why do you open the chip?

1. Chip failure analysis.The chip fails during actual use.In order to determine the cause of the chip failure, the engineer will open the packaging.

2. Reverse analysis.Sometimes the competitors' chips are opened to study the design, architecture and manufacturing process of opponent chips.

How to open the chip of plastic sealing?

There are generally two methods: chemical opening and laser opening.

Chemical opening: Generally use chemical reagents (such as smoke nitric acid and concentrated sulfuric acid) to corrode the packaging material to remove the packaging layer.The advantage is that the cost is low, but it is difficult to accurately locate.

Laser opening: Use laser equipment to remove packaging materials. This method has high precision and fast characteristics, suitable for handling various types of metal connectors such as aluminum, copper, and golden lines.Compared with chemical methods, the laser method is more accurate, and the amount of chemicals use less.
