Information transfer：
The product is designed through two pass
through bridging technology to achieve the antenna solder joints LA and
LB around the chip solder joints, ensuring the reliability of the
subsequent gold wire bonding process.
Advantage：
The process of making card is simple, and the efficiency of card making is improved.
To solve the problem of product deformation caused by welding and improve the quality of products.
Solve the problem of short circuit and circuit breakage caused by welding, and improve the product's good rate.
The conducting hole is used to replace
the copper plating process by the process of conductive body filling,
which reduces the cost, and the process is more environmentally
friendly.
