First, the concept
Circuit board, also known as PCB, is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components.
Circuit board sample production refers to the trial production of printed circuit boards before mass production. The main application is the process of small batch trial production to the factory after the electronic engineer completes the circuit board design, which is the production of circuit board samples. The production quantity of circuit board samples generally has no specific boundaries. Generally, engineers call circuit board samples before the product design is confirmed and tested.
The products in the PCB market are constantly changing. Time is a very important factor in this industry. Delivery and quality are the hard strengths of the factory and are the most popular among engineers and factories. Nowadays, the circuit board factory generally provides expedited service, and the fast factory is also required to have a normal delivery period of 2 days. For example, in FASTPCBA in Shenzhen, China, all the samples are expedited, quality control, engineering, production, real-time monitoring and sample progress, and our advantage lies in advanced production equipment: MYDATA-600, no need to open steel mesh, automated production, province Time and effort, precision boutique.
It is the trial production of the engineer before the product design is not completed and tested. The quality cannot be ignored. From raw materials, drawing, to production, testing, quality control, etc., every link needs to be strictly checked. For example, in general, for ordinary double-panel, the sheet material generally has FR-4, aluminum substrate, CEM-1, etc., the thickness of the sheet is from 0.4mm to 3.0m, and the thickness of copper is 0.5oz to 3.0oz. The difference is very large. At present, the better materials used by the manufacturers are imported raw materials.
With the development of the industry, the price of PCB sample production and small and medium batch production is not lower. At present, many sample companies, such as Czech Republic, cancel all the filming fees for proofing/small batches, and the film fee has withdrawn from the historical stage. Completing challenging tasks with challenging prices, this will be the price trend for the next board proofing.
Pcb assembly reflow soldering process requires that the pads of both chip components should be independent pads. When the pad is connected to a large-area ground wire, the cross-laying method and the 45 ° -laying method should be preferred; the wire drawn from the large-area ground wire or the po...
A very strange phenomenon has recently been discovered. Many companies are currently consulting with PCBA to manufacture this piece, some are very professional and some do not understand. It is equivalent to the South Pole and the North Pole. I roughly analyzed what might be because the current s...
Medical robots refer to the role of intelligent devices to replace some people. For example, surgical robots, rehabilitation robots, etc. Medical robots are essentially intelligent devices, but they can independently operate some plans through programs compiled by engineering personnel. For some ...
