PCB is a lot of electronic equipment in the process of assembling production indispensable key, companies are in the purchase of goods to quality have higher regulation, have to ensure the quality after PCB which can promote electronic equipment performance indicators, also can make commodity more perfect function main performance can prevent delayed a variety of conditions.Below discuss to distinguish the quality of PCB board several levels of content:

First, distinguish from the appearance

PCB in the process of production need through a variety of harsh processing making to meet, from CNC machine hole to hand washing, drying, barrel plating to stick at the bottom of screen printing screen top line and the whole process of each working procedure is endangering the whole PCB production and processing quality, in order to distinguish from the appearance quality, developing step by step to identify can significantly physical printing ink cover in a timely manner, Copper surface without air oxidation condition in addition all surface invisible change condition can be in line with the quality provisions.

Second, from the size and thickness of the resolution

Application specification is not the same as the size of the PCB are technology and its thickness specification, the customer could not tell the same product quality standard to carry out the inspection according to specification, see its thickness size of PCB specification model is consistent with the specification, can do technical standards on its size and its thickness on the application of quality of goods is ensured.

Third, from the components of the solidity of welding

PCB installed on dozens of various electronic components, every electronic components often have exclusive role into full play, to ensure that the quality of the whole PCB do good, the application of shock may dictate all the electronic components welding welding strong is not easy to fall down, the other components sorted the whole order be clear at a glance, This is all can be used to distinguish the quality of the PCB board related content.

Because PCB board is the key electronic equipment assembly equipment, therefore for the application of strict requirements for quality. Therefore proposed the customer need to select the choose and buy quality is to ensure that professional manufacturers to carry out the purchase of PCB technology, manufacturers have not only automation technology, high quality production equipment and production lines, and in the relevant manufacturing process with strict quality control, can guarantee to produce high quality PCB products of high quality for all consumers.
