An accurate procurement management planning economy can accurately predict and master the production and development plan of an enterprise, and enable Chinese enterprises to minimize the occupation of procurement funds on the premise of meeting their own
the prices of PCB board and components in the Chinese market are basically public information and transparent for enterprises on major network platforms, which can be referred to through comparative study.
PCB testing has become an indispensable part of the circuit board manufacturing process. It finds the problem in time, assists the staff to deal with it quickly, and ensures the high quality of PCB.
It is a kind of pin-free or short lead appearance assembly components (SMC/SMD, Chinese known as chip components) installed in the Printed Circuit Board (PCB) appearance or other substrate appearance, after reflow welding or immersion welding and other me
To prevent warping, design engineers must balance the copper pattern on each layer of the circuit board with the area of the circuit. Design engineers must also balance component layout, assembly distribution, and heat distribution to reduce warping.
If the PCB is warped, that is, uneven, the machine's inability to maintain a constant height when releasing the component while placing it on the board affects the accuracy of placement, especially for fine-spaced components.
The main application is the process of small batch trial production to the circuit board factory after the electronic engineer has planned the circuit and completed the production of PCBA, that is, PCBA proofing.
the best way to solve the heat dissipation is to improve the heat dissipation capacity of PCB aluminum substrate in direct contact with the heating element, through the PCB board to conduct out or send out.
PCB is one of the important components of the electronic industry, the industrial output value accounts for about a quarter of the total output value of electronic components, the largest proportion in each electronic component subdivision industry
Because the aluminum base material has excellent cooling effect, the heat dissipation in the circuit process is evaporated in time, prolong the service life of components, so that the circuit is more stable and durable.
From the development trend of various regions in the world, after large-scale restructuring, migration and technological upgrading, domestic PCB and FPC production and processing enterprises seize the opportunity of transferring electronic products to the
PCB copying board is to scan the circuit board, record the location of the components in detail, and then remove the components to arrange the material purchase, and scan the empty board into pictures, processing and restoring to the drawing file.
