What are the factors that affect the price of PCB proofing?
There are many factors affecting the price of PCB proofing, including pcb board materials, production processes, different difficulties, customer needs, regions, payment methods, manufacturers, etc. Here let me give you a detailed introduction.
First, pcb board material different caused by different prices. Board material generally FR-4, CEM-3, etc., the board thickness from 0.6mm to 3.0mm, copper thickness from ½ Oz to 3Oz different, these will cause the cost gap. In terms of solder resist ink, ordinary heat-set oil and photographic green oil also exists a certain price difference.
Second, the use of different production processes caused by different prices. Not the same production process will cause different costs. For example, gold plating and spray tin plate, the production of the shape of the gong (milling) board and beer (punch) board, the use of silk screen lines and dry film lines, etc. will form a different cost.
Thirdly, the different difficulty of proofing causes different prices. Even if the material is the same, the process is the same, but the difficulty of proofing will also cause different costs. Such as different hole diameter, line width and line spacing of two different boards, will also cause different production costs; because of the difficulty of proofing the board scrap rate is higher, the cost is bound to increase.
Fourth, the different requirements of customers will also cause different prices. The level of customer requirements will directly affect the sample of the finished rate, such as a board according to IPC-A-600E, class1 requirements have 98% pass rate, but by class3 requirements may only 90% pass rate, thus causing different costs of the board factory.
Fifth, different PCB manufacturers caused by the different prices. Even if the same product, because of different manufacturers of process equipment, technology levels are different, will also form different costs.
Sixth, other factors caused by different prices, such as expediting fees, collocation fees, labor, water and electricity plus management costs, logistics costs, etc..
In short, the price of PCB prototyping is the most special and complex of all industries, from the opening, pressing, forming, all the way to FQC, packaging, completion of storage, based on each process input material costs, labour costs, manufacturing costs and other step-by-step accounting, and then based on the order product number in batches of cumulative costs. The standard rates for different types of products will vary, and for some products such as blind submerged boards, sunken gold boards, aluminium substrates, ceramic substrates, etc., special calculation methods must be used due to the specificity of the process or material.
