IC chip detection and identification

IC chip detection and identification

1. Understand the working principle of integrated circuits and related circuits before testing. Before inspecting and repairing integrated circuits, you must first be familiar with the functions, internal circuits, main electrical parameters 2020-02-17
How IC chips use nitrogen cabinets to prevent oxidation

How IC chips use nitrogen cabinets to prevent oxidation

The nitrogen cabinet has dehumidification and anti-oxidation functions. You only need to put the IC chip in it, but if it is okay, dont open the cabinet door often. This will make it easier for outside air to enter the cabinet, which will no 2020-02-17
How to determine if the IC pins are oxidized?

How to determine if the IC pins are oxidized?

I. Check board method: 1. Observation method: whether there is burning paste, burning out, blistering, board surface disconnection, socket rust. 2. Meter test method: Whether the + 5V, GND resistance is too small (below 50 ohms). 3. Power- 2020-02-17
How should IC chips be saved?

How should IC chips be saved?

It should be stored in a metal box to prevent static electricity damage and effectively shield electromagnetic waves and microwaves from harming components. The metal box is best made of copper, followed by aluminum, and iron has the worst e 2020-02-17
What are electronic components

What are electronic components

Electronic components are a general term for components and devices. Electronic component: refers to a finished product that does not change its molecular composition during factory production and processing. Because it does not generate ele 2020-02-17
How to distinguish between IC multi-component, single-chip and multi-chip?

How to distinguish between IC multi-component, single-chip and multi-chip?

1. Monolithic integrated circuit It is a type of integrated circuit that is integrated and indivisible on the silicon wafer (or other substrate) using a semiconductor planar process such as resistors, capacitors, and diodes. So it is called 2020-02-17
What is the difference between a chip and a CPU?

What is the difference between a chip and a CPU?

The difference between the two is that the chip integrates upper peripheral devices. The CPU does not have peripheral devices (such as memory arrays). It is a highly integrated general-purpose processor. The CPU is a digital chip, which is j 2020-02-17
How to distinguish authenticity from imported ICs?

How to distinguish authenticity from imported ICs?

Imported ICs generally look at the label Date code on the packaging, and those that are not unpacked are generally original. If it is unpacked, the following methods are for reference. The main method to distinguish between genuine and refur 2020-02-17
