Circuit board PCB processing is OEM OEM products, different customers customized products are not the same, there is little sharing products, on the other hand, out of consideration of quality, some customers may will specify the use of a manufacturer of the substrate, or ink, in order to achieve the quality and cost control requirements, so PCB processing exist and volatile prices.
PCB price is composed of the following factors:
One, PCB materials caused by the diversity of prices.
To ordinary double sided board, for example, sheet generally FR-4, CEM-3, thickness from 0.6 mm to 3.0mm ranging from, copper thickness from 1Oz to 3Oz different. All of these in the sheet a on resulted in the huge price difference, in terms of solder resist ink, ordinary oil thermosetting and photosensitive green also exists with a certain price difference and different materials caused price diversity.
Two, PCB used in the production process of the diversity of prices.
Different production processes will result in different costs. Such as gold plate and HASL, make the form of Gong (milling) plate and beer (red) in by screen printing line and dry film line etc. will be the formation of different cost, leading to price diversity.
Three, PCB itself is difficult to make the price diversity.
Even though the same material, the same process, but the difficulty of the PCB itself will result in different costs. As two kinds of circuit boards have 1000 holes, a board aperture are larger than 0.6mm and another piece of plate aperture were less than 0.6mm will form different drilling cost; such as two kinds of circuit boards to another of the same, but line width from different, a were greater than 0.2mm, a were less than 0.2mm, will also be made into different production costs, because the difficulty of the blackboard newspaper waste rate higher, cost is bound to increase, resulting in the diversity of the price.
Four, different customer requirements will result in different prices.
Customer requirements of high and low rate of finished products will directly effect the plate plant, such as a plate according to the IPC-A-600E that Class1 requirements 98% pass rate, but according to class3 requirements may only 90% pass rate, resulting in plate plant of different costs, resulting in product prices and changeable.
Five, PCB manufacturers caused by different price diversity.
Even with a product, but because of the different technologies and equipments of different manufacturers, the technical level, the formation of different cost, nowadays many manufacturers like production gold plate, because the process is simple, low cost, but there are also part of the manufacturers in the production of gold-plated board, scrap increases, resulting in cost and improve, so they prefer production HASL and they HASL offer instead than gold plates are low.
Six, different payment methods caused by price differences.
Currently PCB board factory will generally be different adjustment of PCB price, the range of 5%-10% range, which also caused the difference in price.
Seven, regional differences in price diversity
At present, from the geographical location, from the south to the north, the price increases by the potential of different regional prices have a certain difference, so the regional differences also caused the price of how to calculate the price of PCB quotes!
1, sheet metal costs (different plate costs are different)
2, the cost of drilling (the number of holes and the size of the pore size of the impact of drilling costs)
3, process costs (the board of different process requirements lead to the difficulty of the process is different, and the price will be different)
4, artificial water and electricity and management costs (the cost depends on the individual plant cost control, relatively speaking Taiwan funded factories on the low countries constitute the basic of these, as raw materials prices, well now tends to be stable, prices is unlikely.
Eight, on the plate: the impact of the price of the following points:
1. The plate material: FR-4, CEM-3, this is our common double-sided and multilayer board, his price and the thickness of the plate and the plate middle copper foil thickness and fr-i, CEM-1 these is our common single plate material a, and the material price is higher than the above double-sided, multilayer board vary greatly.
2, plate thickness, the thickness of which we are common: 0.4, 0.6, 0.8, 1, 1.2, 1.5, 1.6, 2, 2.4, 3, 3.4, and we are not a big difference in the thickness of the conventional plate.
3, copper platinum thickness will affect the price, copper platinum thickness is generally divided into: 18 (2/1OZ), 35 (1OZ) 70 (2OZ), 105 (3OZ), 140 (4OZ), etc.
4, raw material suppliers, common and commonly used to have health benefits: \ \ international Kingboard process cost etc.:
Nine, PCB circuit board production of other factors
1, to look at the PCB above the line, such as the line dense line (in 4/4mm) below, the price will be calculated
2, there is a BGA board, as the cost will be relatively increased, in some places is BGA another calculate how much money a.
3, to see what is the surface treatment process, our common: spray tin (HASL), OSP (green board), sprayed pure tin, tin, silver, gold, and so on, of course, surface process, the price will be different.
4, but also the technology standard; we used is: IPC2, but customer requirements will be higher, (such as Japan) our common have: IPC2, IPC3, enterprise standard, army standard and so on, of course, the higher standard, the price will be higher and higher.
PCB industry sold every piece of PCB are customized. Therefore, PCB quotation need to cost accounting, also need to refer to the imposition of computer automatic PCB calculation, in the standard size of the copper clad laminate typeset material use rate is made of synthetic quote.
PCB industry cost calculation is all industries is the most special, the most complex, from materials, plate, forming, has been to FQC, packaging, the completion of storage and need to accounting step by step into every process of material cost, labor cost, manufacturing cost basis, according to the product order batch number cumulative cost. And different types of products, the standard rate of the process will be different. For some products such as blind hole plate, heavy plate, pressed copper plate, because of its process or all of the material, the requirements must be used in some special calculation methods. In the same way, the size of the drilling nozzle used in the drilling process will affect the cost of the product, which directly affects the calculation and evaluation of WIP cost and scrap cost.
