It's very important for those commodity managers to understand the critical PCB process. Let's see how PCB manufacturer China Honlynn Circuits tells you . This part will be focus on the conventional rigid PCB process and we will continue this for flexible PCB fabrication in next section.

Solderability issue is one of the major quality issues for electronic assembling and brings big impact to quality and cost of your products. If you have solderability issue with your PCB board supplier you will need to work with them to find out the root cause at first. Now let’s see how PCB manufacturer China Honlynn Circuits analysis the root cause of this quality defect.

We all know the demand changes quickly in recent years and this affects your production with lots of order pull ins & push outs and this brings challenges to material inventory management. It's very important to understand the shelf life of the raw material and electronic components including the packed finished PCB with different surface finishes. Let's learn from PCB manufacturer China Honlynn Circuits so you could know when your PCB inventory has to flow to the assembly lines before they

In the surface treatment of circuit boards, there is a very common process called immersion gold. The purpose of the immersion gold process is to deposit a nickel-gold coating with stable color, good brightness, smooth coating and good solderability on the surface of the printed circuit board. In short, immersion gold is to use chemical deposition to produce a metal coating on the surface of the circuit board through chemical redox reactions.

High-density multi-layer circuit board manufacturers: products cover 1-32 layers, multi-layer boards, heavy copper boards, glass fiber boards, high-frequency microwaves and other special PCB boards.

PCB high frequency board is a special circuit board with high electromagnetic frequency, used for high frequency (frequency greater than 300MHz or wavelength). Generally speaking, a high frequency board can be defined as a circuit board with a frequency higher than 1GHz.

Ceramic board, due to its heat dissipation performance, current carrying capacity, insulation, thermal expansion coefficient, etc., is much better than ordinary glass fiber PCB board, so it is widely used in high-power power electronic modules, aerospace, military electronics and other products.

Compared with the characteristics of conventional circuit boards, multi-layer circuit boards have the characteristics of thicker boards, more layers, denser lines and vias, larger unit sizes, and thinner dielectric layers. And it will be more stringent for innerlayer space, innerlayer alignment, impedance control, and reliability requirements.
