What Are The Factors Affecting The Variability Of PCB Price

- Aug 11, 2017-

A. PCB materials used to create a variety of prices

Bluetooth PCB manufacturers to ordinary two-panel as an example, the board is generally FR4 (health benefits, Jian Tao, National Ji, three prices from the top down), plate thickness from 0.2mm to 3.0mm, copper thickness from 0.5oz to 3oz different, all of these on the sheet of a huge price difference; in the resistance welding inks, ordinary hot-fixing oil and photosensitive green oil also exist a certain price difference.

Two. Different surface treatment processes cause price diversity

Common: OSP (antioxidant), lead-sprayed tin, lead-free tin (environmental protection), gold-plated, immersion gold and some combination process, etc., the above process prices more expensive.

Three. PCB itself difficult price diversity caused by different

There are 1000 holes on both boards, and the aperture of a board is greater than 0. The aperture of 2mm and another plate is less than 0.2mm will create different drilling costs; But the line wide line distance is different, one is more than 4mil, one is less than 4mil, also can cause different production costs; Secondly, there are some not to go the design of ordinary board process is also to add money, such as half hole, buried blind hole, plate medium hole, key plate printing carbon oil.

Four. Different thickness of copper foil cause price diversity

Common Copper Platinum Thickness has: 18um (1/2oz), 35um (1OZ), 70um (2OZ), 105um (3OZ), 140um (4OZ), etc., the above copper foil thickness more expensive.

Five. Customer Quality acceptance Standard

Commonly used is: IPC2, IPC3, Enterprise standard, military standard and so on, the higher the standards, the higher the price.

Six. Mould fee and test stand

(1) Die costs, model with small quantities of the general plate factory is used in the drilling and milling shape, will not add additional milling edge, in larger quantities when the request to open the mold punching plate, so there is a set of mold costs, the general price of the plate factory in 1000 yuan.

(2) Test fee: The model generally uses the Flying needle test, the Board factory generally collects the test fee 100-400 yuan unequal; the batch will open the test stand to measure, the Test Rack General Board factory quotation in between 1000-1500 yuan.
