The process of moving a program to the internal storage space of the chip is generally divided into offline burning and online burning offline burning. These chips are compatible with chips in different packages through various adapters, and the chips can
which is equivalent to reviewing the schematic diagram, modifying the scheme for design, and si simulation at the same time. There are many types of power supply with small voltage and large current on the board.
The most important material for printed circuit boards is copper, from which most boards are made.
ERP project implementation success depends on three points of technology, seven points of management, twelve points of data. Visible, ERP system in the importance of basic data collation.
Ink is gelatinous when standing, and is touched when the viscosity changes a property, also known as shaking, anti flow hanging
In the future market development, circuit board maintenance technology has been accepted by more and more people. Therefore, it also promotes the development of circuit board maintenance industry.
This paper introduces a new maintenance tool, on-line tester, and focuses on the function characteristics of the tester and the methods and steps of using it to repair the circuit board.
The lead inductance of patch resistors and capacitors is greatly reduced, which has great advantages in high frequency circuits. The disadvantage of surface mounted components is that they are not easily welded by hand.
The fabrication of microholes on the circuit board and the molding of the circuit board as the hot spot of laser processing have created a sensation in the world, laser processing with its superiority has brought huge benefits.
In the printing industry, photo platemaking is often used to produce pictures on paper. That is, by taking photos, the picture of the bottom plate, etched on the copper plate or zinc plate, with this copper plate or zinc plate, you can print a lot of pict
