Why your PCB so expensive? (I)

Part: various factors that affect the price of a PCB board

The price of PCB has always been a puzzle to many buyers, and many people will wonder how these prices are calculated when placing orders online. Let’s talk about the components of PCB price together.

 

  1. Different materials used in PCB lead to a variety of prices

For example, Ordinary double panel, the plate generally has FR4 (Sheng yi, Kingboard, Guoji, three prices from the top to down), plate thickness from 0.2 mm to 3.0 mm, copper thickness from 0.5 oz to 3 oz, all these in the plate material on a huge price difference; In the resistance ink, ordinary thermosetting oil and photosensitive green oil also exists a certain price difference.

2.Different surface treatment processes lead to a variety of prices

Common surface treatment process: OSP (oxidation resistance), there is HASL, Lead-free HASL (environmental), gold plating, Immersion gold and some combination process, and so on, the process price is more expensive in the future.

 

3.PCB itself caused by different difficulty of price diversity.

There are 1000 holes in both circuit boards. If the hole size of one board is greater than 0.2mm, the hole size of the other board is less than 0.2mm. If two kinds of circuit boards are the same, but the line width and line spacing are different, one is larger than 4mil and the other is smaller than 4mil, it will also cause different production costs. Next still have a few do not walk the design of common plate craft flow also is to add collect money, for example half hole, bury blind hole, dish hole, press key plate to print carbon oil.
