The main factors that affect PCB prices are:
1. Cost distinctions are based on double-sided PCBs. Boards are usually fr-4, cem-3 etc. Board thickness can vary from 0.2mm to 5.0mm and copper thickness from 0.5oz to 3oz. These differences have led to significant price differences. In solder mask oils, there are specific costs between thermosetting oils and green photosensitive oils.
2. PCBs use a variety of manufacturing processes, which will result in varying costs. The production of tin-sprayed and gold-plated boards, or the shapes of milling boards (milling boards) and beer boards (red boards), and the use silk screen lines or completely dry film will all have different costs.
3. Rate difference is due to the difficulty of PCBs. The complexity of the PCB will cause different expenses even if materials and processes are the same. The complexity of the PCB will cause different costs even if materials and processes are identical. If two boards each have 1000 holes, but one board has a size of hole greater than 0.6mm and the other board is smaller, different boring costs will be incurred. It is the difference between the two boards that creates different manufacturing costs. The high scrap prices of hardboards will certainly increase the price, leading to cost differences.
4. Different client requirements in SMT production will also create different costs. The board's result rate will directly be affected by the level of customer need. A board that is IPC-a600e requires a 98% passing rate in class 1. However, if class 3 requirements are met, the pass rate might only be 90%. This will result in different manufacturing costs and ultimately change item prices.
5. Different PCB manufacturers cause cost diversity. Despite the same product, different costs will arise due to the various technological devices and processing levels of producers. The cost and procedure are reduced for some SMT manufacturers, but others produce boards with gold plating, which has a higher scrap rate. They prefer to make tin sprayed board, and the scrap rate is less than gold plated boards.
6. Differential price effects of different repayment methods. PCB handling facilities change PCB prices based on different repayment methods. These can range from 5% up to 10%. This creates additional cost differences.
7. Regional distinctions cause value diversification. Locally, today, the cost of living tends to increase from south to north. Different regions have different costs, which is why they also differ in rates.
