In the PCB industry, the price of each production is different, and there are many factors. So, what are the factors affecting the price of PCB? 1. Materials Just like other products, the prices of products made from different materials are not the same, and the PCB is also the same. Taking ordinary double-panel as an example, the sheets generally have FR-4, CEM-3, etc., the thickness ranges from 0.6mm to 3.0mm, and the thickness of copper varies from 1Oz to 3Oz. The difference in sheet material causes huge price difference. . 2. Production Process Different production processes will result in different costs. Such as gold-plated plate and tin-plated plate, the shape of the 锣 (milling) plate and beer (punching) plate, the use of silk screen lines and dry film lines will form different costs, resulting in price diversity. 3. Difficulty Even if the materials are the same and the process is the same, the difficulty in PCB production will result in different costs. If the line widths of the two types of circuit boards are different, one is greater than 0.2 mm and the other is less than 0.2 mm, which also causes different production costs. 4. Other factors In addition to the above factors, there are other factors, such as customer requirements, manufacturer's process equipment, packaging methods, shipping methods, payment methods, geography, etc., which will affect the final price. Among the above factors, the material factor is the most important. In terms of sheet metal, the main factors affecting the price are as follows: 1. Sheet material FR-4, CEM-3, which is a common double-sided and multi-layer sheet. The price is related to the thickness of the plate and the thickness of the copper in the middle of the plate. FR-I, CEM-1, is a single-board material, and the price is much different than that of multi-layer boards. 2, sheet thickness Common thickness: 0.4, 0.6, 0.8, 1.0, 1.2, 1.5, 1.6, 2.0, 2.4, 3.0, 3.4, thickness is different, the price is also different. 3, copper and platinum thickness Copper and platinum thickness is generally divided into: 18 (2 / 1OZ), 35 (1 OZ) 70 (2OZ), 105 (3OZ), 140 (4OZ) and so on.
