A virgin plate, also known as bakelite, is a plate bathed in copper on one side, since an electronic circuit can be made on this plate.
Global PCB raw material costs are rising, JLCPCB never takes undue advantage of Non-A grade board. Last year the whole PCB manufacturing industry faced raw material shortage issues. Many PCB companies sent internal letters to their customers stating that copper prices have risen by more than 50%, copper foil processing costs have risen by more than 20%, and demand continues to increase, resulting in a surge in copper foil prices. The current copper foil prices Compared with the third quarter of last year, it has increased by about 50%
Nanya company issued a notice about growing price, saying that the prices of CCL-related raw materials including LME copper, copper foil processing fees, epoxy resin, and fiberglass cloth continued to increase in price, coupled with tight supply and demand, in order to ease Due to cost pressure, it is planned to increase the price by about 15%-20% of the total transaction amount, which will take effect from April 1st this year."
This kind of shortage caused a battle for grabbing raw materials. But JLCPCB never takes undue advantage of the Non-A grade board. The raw material cost growth situation seems to slow down in June 2021. JLCPCB's single, double boards and small-volume board overseas prices have been lowered from June 5th, 2021 as long as the price of the core raw materials of the circuit board decreases. Cost increment for raw material is a daunting matter. The sheet material is the core and main raw material of PCB, accounting for about 6% of the cost. Using a piece of A-grade raw material and using a piece of non-A-grade material is a great temptation for PCB manufacturers to make profits. If you want to save the cost of raw materials, it is also the most costly raw material.
The price difference between the two is as high as $10/?. It is PCB suppliers' duty to use international standard materials, however, too many non-standard materials appear in the global market. The supply of downstream products is scarce, leading to rising raw materials. Therefore, in order to protect their interests, some companies use A3-grade materials in private. Some companies even show customers that they use A1-grade raw materials. What problems caused when customers use A3 grade raw boards for ordinary home appliances, industrial, and automotive electronic boards? Take the LED light board as an example, LED will be short-circuited, and the light will be faulty. PCB is the carrier of electronic components and is an indispensable part of various electronic products. It is easy to distinguish that A1 grade materials are better than non-A grade materials just by considering different materials from the perspective of functional properties.
To understand this section, we must know a little history. The history of the development of printed circuits is not as old as that of the industrial revolution, around 1950 is when the first PCBs began to be commercialized, however, in the early 1900s it was when the first attempts at PCB designs emerged.
The human being had the need to have electrical equipment that had a reduced size, before this the search began to replace the complex and extensive cable connections with electronic components.
Technology has advanced and electronics are not left behind, as can be seen in the previous image, the first printed circuit boards were totally disorganized, large, heavy and not very efficient, but even so, they fulfilled their function, this gave way to the first electrical and electronic devices, such as the first radios, televisions, among others. All components of these plates were through hole.
Man required a little more to be able to develop and innovate much more, so with the passage of time and after a lot of research, trials and errors, he managed to develop quite impressive technology, surface mount circuits, also multi-layer PCBs, This was the beginning of all the development that we have today, since they allowed to miniaturize all the components of a printed circuit board with through hole components, to a simple board much smaller, efficient and which allows the design in both faces of the plate, reducing the size considerably, today these circuits can be found from a simple calculator, to the computers of space shuttles, through our cell phones, computers, microwaves, refrigerators, stoves, headphones, televisions, In any device that works with electricity we can find printed circuits, have you thought that it would be n Our existence as humans if we didn't have a simple printed circuit board? Impressive!!
