What do PCB copying boards need to provide: Usually, simple single and double panel copying boards only need to provide one set of samples. If it is multi-layer board, it is better to provide two sets of exactly the same samples, which is convenient for l
Circuit board design and production process: 1. Preparation of production materials, 2. Circuit board production and manufacturing, 3. Production and design
When selecting circuit board components based on component packaging, the following needs to be considered: component packaging selection. Grounding methods. Virtual component packaging. Verify complete material list data. Sort. Excess gate circuit.
The PCB board where the component is placed is placed into the machine from one end. On a double-track conveyor belt, the circuit board of the newly placed component passes through the hot and cold zones of the reflow furnace, precisely controlling the me
In the increasingly fierce market competition at present, PCB manufacturers are trying to reduce the cost, in order to achieve a larger market share, in the pursuit of reducing the cost, often ignore the quality of the circuit board.
The effect of horizontal perforation electroplating in machining multilayer circuit boards is far inferior to that of vertical perforation electroplating.
With the high density interconnection design of PCB board and the progress of electronic technology, carbon dioxide laser processing equipment has become an important tool for PCB board manufacturers to process microholes.
The drawing maintenance method refers to the schematic diagram, analyzes the circuit principle and signal direction, and then tests the signals on the key points. Professional maintenance companies maintain circuit boards almost without drawing.
The final electrical conductivity, impedance test and solder and thermal shock tolerance test are carried out on PCB before packaging. And bake to eliminate the moisture and thermal stress absorbed by PCB in the process, and finally packaging and shipping
According to customers' individual needs, we can exchange the positions of components in the board, rearrange the circuit and pcb design layout, etc., in order to achieve the desired effect of customers.
Printed Circuit Board Quality Standards and Performance Specifications Series Manual. Includes the quality standards and performance specifications set by the Printed Circuit Board Association of America for all printed circuit boards.
Many customers will require the production of halogen-free board, halogen-free board is an environmentally friendly material, halogen-free circuit board is used by the substrate is processed with halogen-free raw materials.
