China Harvar Group will participate in the 2018 International Circuit Board and Electronic Assembly South China Exhibition held at the Shenzhen International Convention and Exhibition Center from December 5-7, 2018. Exhibition Hall No. 1 1D01.
The highlights of this exhibition are:

The world's original new weak alkaline chemical silver process
Product Features
1, the plating liquid does not contain nitric acid, no biting copper wire and side erosion problems.
2, plating liquid does not contain corrosion inhibitors and osmosis.
3, the plating solution is a whole mixture system, the resulting silver layer is a pure silver layer, does not contain carbon or organic matter.
4, pure silver layer welding, there are no bubbles in the welding ball, high welding strength.
5, plating liquid can be plated for 1-5 minutes to ensure that silver is fully plated in the blind hole without biting the copper wire and side erosion.
6, the plating solution is slightly alkaline but will not attack the green paint, pure silver layer anti-discoloration performance is excellent, no need to waste non-sulfur gloves and non-sulfur paper.

China's leading horizontal cauldron process
Horizontal copper VS direct plating
1. Porous metallized conductive substrate: copper, good conductivity;
2. No electrolytic Redox deposition;
3. No post-microerosion process is required;
4. The drug water system has a long life and good conductive stability.
Horizontal caving copper VS vertical caving copper
1. Closed solution reaction system, more environmental protection;
2. Tablet feeding method;
3. Potion holes rely on equipment spraying, water knives and ultrasound;
4. Short process time;
5. The speed of the drug water cycle is fast;
6. Short washing cycle;
Can be used on various FPC boards, R-flex& PCB and so on.

China's leading horizontal cauldron process
1. Do not use the carcinogen formaldehyde, more environmentally friendly;
2. Less water consumption, lower energy consumption, less waste generation, and more protection of the earth;
3. The quality fully meets the IPC 600 standard and the price is high;
4. Unique equipment design, more suitable for high aspect ratio through the hole process;
5. Process flow is more suitable for fine line production;
6. More concise process steps, lower PCB manufacturing integrated costs;
7. Use horizontal equipment to reduce operator labor intensity and beautify the work environment;
8. The product uses a cylinder exchange cycle, and the amount of treatment per liter of catalytic tank can reach 18 M <UNK> / L or 30 days.

Live activities are wonderful and rich: 1. During the exhibition, I will have the opportunity to get a beautiful gift!
2. More opportunities to participate in Zhongguohafu lucky grand raffle activities, gifts rich, first come, first served! Try your luck.
More surprises for you!
