Our Service:

We can offer below services to our cutomers.

1) PCB Design

We have experienced engineers who used to work in HuaWei and Cisco. They have rich experience in PCB design and layout. If cutomers want to outsource the pcb design work to suppliers, we can take it.

2) PCB Manufacturing(Main Business)

PCB manufacturing is our main business. We have two factories which produce pcbs and we can produce very rich kinds of pcb, like HDI pcb, multilayer pcb, rigid-flex pcb, half hole pcb, thick copper pcb, hard gold pcb etc. This business is our main profit resources.

3) Components Outsourcing

Since our marketing office locates in ShenZhen City, we have very rich suppliers resources for componenets. If our customers want us to buy components, we can also do that.

4) PCB Assembly

We have very close brother factories which offer SMT and DIP services. For some customers, they only need samples pcba and they do not want to find too many suppliers.

Questions&Answers:

Question:What Is PCB Measling?

Answer:

Measling is the occurrence of discrete white spots in the base laminate material of a PCB. Measling usually occurs when the resin is not properly applied to the board during the lamination process. These defects appear during the PCB production cycle and signify a malfunctioning board.

A small amount of measling can be tolerated on printed circuit boards however when excessive this can degrade electrical and overall performance of the board. A combination of moisture and other contaminants is responsible for measles.

Adopting proper production techniques can help prevent its development. However, sometimes PCB Measling can occur during the life of the board due to mechanical stress. The finish on the glass fabric also contributes to measling. A higher the surface tension finish on the board, results in better wetting and better resistance to measling.

How to prevent PCB Measling?

• By adopting the well-managed manufacturing process
• By ensuring proper temperature and resin control methods
• By ensuring the quality of surface finishes and storing the PCBs in dry space
• Maintaining the board temperature before proceeding for thermal processing

Measling Test Procedure:

Various test methods are used to validate the measling defect. One is to expose the laminate to moisture prior to its immersion in 500 degrees Fahrenheit solder paste. If the laminate passes this test, then it will normally go through the etching and soldering process without measling and the appearance of white spots.

Witgain Technology Ltd was established in 2007 in ShenZhen City. After over 10 years development, the company now posses two factories. One factory located in HuiZhou City which is near to ShenZhen. The other one locates in JiangXi Province. Marketing dept still locates in ShenZhen City.

We have about 300 employees in two factories and the monthly output is around 30000m2. Our marketing orientation is to make high difficult and special treatment pcb. Even though, we still accept normal 2-layer and multi-layer pcb orders. Our products cover simple double layer pcb, multi-layer pcb, HDI pcb, rigid-flex pcb, fpc, ceramic pcb, heavy gold/copper pcb etc. Wide product ranges and flexible order quantities allow us to satisfy most customer's demands. 

Quality and technology is what we value most and we will never stop improving our capabilities. Our customer's satisfication is always what we are seeking for.
