Company Advantages
1. thick copper pcb is strongly recommended for its printed circuit board assembly design. It is subjected to extreme heat and soldered into place
2. It is of great importance for Rocket PCB to assure the quality of thick copper pcb before packing. The product makes the process of replacing the particular failure components easier
3. All aspects of the product, such as performance, durability, availability, etc., have been carefully tested and tested during production and before shipment. It takes less time in assembling a circuit as compared to the conventional method
4. The product has excellent performance, stable and reliable quality. Its signal paths are well organized and exposed quite well
5. This product guarantees stable performance and long service life. It reduces the component welding points and is possible in the reduction of the failure rate
About our product

Making process control of thick copper board


Drilling aperture

Due to the need to go through two copper plating, the finished product aperture needs to be compensated accordingly

After two times copper plating need to complete the outer layer pattern, soldermask, silkscreen and other processes, so the Pin hole has the corresponding control

 

1, Design of first registration pin hole 3.175mm, ensure the accuracy of the first outer layer

2, Design second time of pin holes, due to after two copper plating the pin hole diameter is smaller, so the original design need to do the corresponding compensation, this pin hole directly affect two times of the outer layer, soldermask, silkscreen registration accuracy

 

First time soldermask control

 

1, Base material position filling ink, guarantee smooth with copper surface

2, Nail bed making, try to print both sides of soldermask at the same time

3, Block Point Network production, requires 36T mesh yarn

4, Printing ink viscosity ≥300dpa.s, ensure that the substrate and copper surface high difference can fill

5, Pre-baked, after printing static 2H or more

6, Contraposition Wash the remaining ink off the line on the development line, line open window unilateral shrinkage 2-3mil to ensure the accuracy of the position

7, After-baking, segmented baking, to ensure that the substrate position of the ink completely cured

 

Second time copper Plating

 

Rough treatment of board surface before drilling and plating, drilling electroplating is the same as double board process , copper plating time 20min , turn off the grinding brush after first time copper plating

 

Second time outer layer pattern

 

Pre-treatment turn off the grinding brush, only over pickling, to prevent the substrate bit copper skin wrinkle, to prevent the film from wrinkling resulting in second graphics seepage plating.
