What should a good PCB board manufacturer possess? What capabilities should a PCB manufacturer possess? What areas should a PCB manufacturer consider.
Is there a problem with the insertion point of the PCB circuit board being too large? Ring free seamless automatic SMT ring free DIP insertion method PCB board assembly method.
Some PCB manufacturers' engineers promote their main product, PCB circuit board mounting, to reduce LED application costs by using many conventional PCB boards.
PCB board size and surface treatment: If the PCB board size is too large, there may be some strange phenomena during SMT surface mounting, and the specific situation of the PCB board.
In order to meet the needs of customers for multi-layer PCB circuit board sampling, Jialichuang PCB factory will process PCB for production after the circuit board sampling is completed. Generally, it uses Myshi component boards, with a default number of layers of 10. The material of the interlayer semi cured sheet is 01mm, and the dielectric grade resin of the single board is pressed together with the bottom copper foil through the surface resin.
Attention: For the convenience of production, it is recommended to make PCBs with relatively deep dimensions (usually over 7 mils), and try to leave larger sizes as much as possible, preferably without through holes.
In addition, in order to prevent the aging of the inner copper foil line during compression, the outer wire should be perforated with holes ranging from 04mm to 06mm, and should not reach the end of the outer wire; During internal wiring, all welding surfaces should be approached with as small angle lines as possible to improve mutual capacitance between signals and stabilize signal integrity.
Before production, PCB assembly designers need to determine a reasonable set of material selection drawings, template specifications and models, and determine their functionality.
According to the sample size and specifications provided by the PCB design company, they are 12 inches, 16 inches, and 32 inches.
The reason for choosing how much Kg to use and choosing isopropyl/PP and tight SNL interlayer insulation oil is because the materials themselves are different, so sometimes they are only parts of some products, while other parts are just some shortcomings of some products, resulting in certain differences in their performance. Based on experience, the reason for selecting alloy materials of different qualities as "shipper products" under the operation mode of quantity is due to poor production process capacity, coupled with the relationship in the field of technology. Currently, there are still some unstable areas, and the reason for the instability of point quantity is due to expensive production costs. Design is only one way to solve this problem.

Purchasing raw materials from customers to sales. This determines the wholesale price and also affects the number of points. If the purchased components are very limited, the price will correspondingly increase.
The number of points at the time of purchase, including the actual board area and material, as well as the size of the circuit board, can also be considered to choose this specification of board, as the performance of the boards we produce is balanced and guaranteed.
We believe that resistance welding and resistance welding strength are required for the electrical requirements purchased, but if it is not a tinned board, it is also normal.
