Over the years, PCB price changes have been familiar with people inside and outside the industry, even though some people with years of experience in the PCB industry may not fully understand the ins and outs of this, so to analyze the main factors affecting pcb price:
-
The diversity of prices caused by the different materials used in PCBs is based on common double-sided boards. Sheets generally include fr-4, cem-3, etc., and board thickness varies from 0.2mm to 5.0mm, and copper thickness varies from 0.5oz to 3oz. All of these have resulted in huge price differences on the sheet material; in solder mask inks, there are also certain price differences between ordinary thermoset oils and photosensitive green oils, and thus the diversity of materials has caused price diversity.
-
The different production processes used by PCBs result in different production processes with different prices that will result in different costs. Such as gold-plated plates and sprayed tin plates, the production of the shape of the milling (milling) plate and beer (red) plate, the use of silk screen lines and dry film lines will have different costs, resulting in a variety of prices.
-
The diversity of prices caused by the difficulty of the PCB itself Even if the material is the same, the process is the same, but the difficulty of the PCB itself will result in different costs. For example, if there are 1000 holes on both boards, the hole diameter of one board is more than 0.6mm and the hole diameter of the other board is less than 0.6mm, different drilling costs will be formed; if the two boards are the same, the linewidth is different. Differently, one type is larger than 0.2mm and one type is smaller than 0.2mm, which also causes different production costs, because the scrap rate of difficult plates is high, the inevitable cost is increased, and the price diversity is thus caused.
-
Different customer requirements will also cause different prices The level of customer demand will directly affect the plate production rate, such as a board by ipc-a-600e, class1 requirements have a 98% pass rate, but according to class3 requirements may be only 90% The passing rate, resulting in different costs for the mill, eventually led to a change in the price of the product.
-
The diversity of prices caused by different PCB manufacturers even if the same product, but because of different manufacturers of technology and equipment, different levels of technology, will also form a different cost, nowadays many manufacturers like to produce tin spray plate, because the process is simple, low cost, but Some manufacturers also produce gold-plated plates, resulting in higher scrap rates and higher costs. Therefore, they prefer to produce tin-spray plates, so their prices for tin-spray plates are lower than those for gold-plated plates.
-
The price difference caused by different payment methods At present, PCB manufacturers generally adjust PCB prices according to different payment methods, ranging from 5% to 10%, which also results in price differences.
-
Diversification of prices caused by regional differences At present, from the geographical point of view, prices have been increasing from south to north. There are certain differences in prices in different regions, and thus different regions have also caused price diversity.
