Wholesale The high TG printed circuit board comes from the best technology in China with good price - Best Technology
In PCB proofing, a layer of copper is bonded on the fr-4 surface. When copper thickness ≥ 2OZ is carried out, it is defined as thick copper plate. Its thickness is different, the actual usable place is also very different .
Capability: We are continued to improve our MCPCB, FR4 PCB & Ceramic PCB manufacturing level to get satisfactory result from customers and ourselves.
Art-of-state Technology: Most of our engineer and operators has more than ten years of experience in PCB industry, so we can produce special such as 20 OZ heavy copper board, 4 layer MCPCB, etc.
Quality Policy: PCB Quality is the core of products. All of engineer & vital department guys has more than five years expenrience in PCB industry, we follow up the default PCB standard, as well as with clients' special request.
Frequently Asked Questions about fr4 tg180
Why does we do surface finishing for PCB?
If you have saw the question "What's surface finishing on PCB?" above,this question will be easy to understand:first,we need to protect copper circuit layer from oxidation and mechanical damage,second,we need to keep the copper solderability and electrical property.
What are the common surface finishing?
For different request,we can do different surface finishing to meet customers.List the surface finishing,that Best Technology Co, Limited have the ability to do for your information. HAL PCB:hot air leveling (HAL),that use Sn to do surface finishing,read more... OSP PCB:Organic solderability preservative (OSP),read more... ENIG PCB:Electroless Nickel/Immersion Gold (ENIG),Immersion gold on pads,read more ... ENEPIG PCB:electroless nickel electroless palladium immersion gold (ENEPIG),read mor
What's surface finishing on PCB?
Usually we manufacturing PCB as copper circuit,but copper oxidized easily,so we will do Soldermask upon copper circuit layer,but when we need welded components on PCB,we will have to make pads,how to protect the pads from oxidation and don't destroy the solderability?We can do surface finishing on PCB.
