This year, the upstream raw materials of the LED display have risen again and again, and the inventory of various raw materials has been in a hurry. Among them, the supply shortage of PCB boards is the most serious, and it has almost reached a state of "unstoppable". PCB board companies have issued notices of price increases, suggesting that the price of circuit boards will increase by 5% to 20%.
Some companies said that the reason for increasing the price of circuit boards is that the prices of raw materials such as upstream copper clad laminates and copper foils continue to rise sharply. So what are the other factors that affect the price of PCB circuit boards?
Other factors affecting the price of PCB circuit boards
It depends on the circuit on the PCB. If the line density is thin (below 4/4mm), the price of the circuit board will be calculated separately;
There is also a BGA on the board, so the cost will increase relatively, and in some places, how much is the BGA;
It depends on the surface treatment process. Our common ones are: spraying lead tin (hot air leveling), OSP (environmental protection board), spraying pure tin, tin, silver, gold, etc. Of course, the surface technology is different, and the circuit board The price will also be different;
It also depends on the process standards; what we commonly use is PC2, but some customers have higher requirements (such as Japanese). Our common ones are: IPC2, IPC3, corporate standards, military standards, etc., of course, the higher the standard, the line The price of the board will also be higher.
Other factors affecting the price of PCB circuit boards
Every PCB sold in the PCB industry is customized by customers. Therefore, the quotation of the PCB boardneeds to be cost-calculated first. At the same time, it also needs to refer to the automatic layout calculation of the PCB computer, and the material utilization rate of the layout on the standard size copper clad laminate is determined. Comprehensive quotation.
The cost calculation of the PCB industry is the most special and complex of all industries. From cutting, pressing, forming, to FQC, packaging, and finished storage, it needs to be based on the material costs, labor costs, and manufacturing costs invested in each process. Perform step-by-step accounting, and then accumulate costs in batches based on the order product number. And for different types of products, the standard rate of the process will be different. For some products such as blind and buried vias, immersion gold boards, and pressed copper seat boards, some special calculation methods must be adopted due to the particularity of the process or all materials. In the same way, the size of the drill bit used in the drilling process will also affect the cost of the product, which directly affects the calculation and evaluation of WIP cost and scrap cost, and the price of the circuit board will naturally be affected.
