Over the years, pcb price volatility has been familiar to people outside the industry, even though some have years of experience in the PCB has also not all staff understand the ins and outs herein below to analyze the main factors affecting the price of pcb:
A, PCB materials used diversity caused by different price
Ordinary double panel, for example, sheet metal generally fr-4, cem-3, etc., from 0.2mm to 5.0mm thickness ranging from 0.5oz to 3oz copper thickness is different, all of which would result in sheet on a a huge price difference; in solder inks, oils and common photosensitive thermosetting there are some green oil price difference, which caused the price of different materials diversity.
The two different production processes, PCB cause the price of Diversity adopted
Different production processes will result in different costs. If gold plate and spray tin plate, making the shape of the gong (milling) plate and beer (red) plates, using screen printing lines and dry lines, etc. will form different costs, causing prices to diversity.
Three, PCB itself diversity of different difficulty caused prices
Even if the same material, the same process, but can also cause difficulty in itself a different PCB different costs. If there are two kinds of circuit board 1000 holes, one board aperture greater than 0.6mm and the other one is less than 0.6mm aperture plate will form different drilling costs; same as the other two kinds of circuit boards, but the line width type A were greater than 0.2mm, less than a 0.2mm, will result in different production costs because of the high scrap rate difficulty plate inevitably increase the cost and cause the price diversity.
Four different customer requirements will result in different prices
Customer requirements will directly affect the level of mill yield, as one kind of board by ipc-a-600e, class1 required 98% pass rate, but may be required by class3 pass rate of 90%, resulting in different costs MILL , leading to changing product prices.
Five, PCB manufacturers prices caused by different diversity
Even the same product, but because of technology and equipment from different manufacturers, different skill levels, will form a different cost, nowadays many manufacturers like spray tin plate production, because the process is simple, low cost, but some manufacturers gilded panels, scrap rate rise , resulting in higher costs, so they prefer to produce spray tin plate, tin plate so they spray quote but lower than gold plate.
Sixth, the payment price differences caused by different
Currently PCB mill will generally be adjusted according to the different ways of payment PCB prices, ranges from 5% -10% range, which also caused the price difference.
Seven regional diversity caused by different price
Currently Geographically speaking, from south to north, prices showed an increasing trend, there are some differences in prices in different regions, and thus also caused the prices in different regions of diversity.
