PCB factory Trident Q2 revenue hits a high record

Thailand’s second-largest PCB maker Trident publishes an announcement in June, new orders and new customers continue to inject, coupled with ongoing new PCB factory capacity out, monthly revenue soared high, reaching 641 million yuan. The monthly increases 5.6% annual growth of 25.2%, the new high record for a single month, the cumulative second-quarter revenue will […]

Flex PCB and Rigid-flex PCB

Flexible PCB or FPC is a patterned arrangement of printed circuitry and components that utilizes flexible-based material with or without flexible coverlay. These flexible electronic assemblies may be fabricated using the same components used for rigid printed circuit boards, but allowing the board to conform to the desired shape (flex) during its application. Rigid-flex PCBs […]

Application of Plasma Surface Pretreatment in PCB Manufacture Process

China plays an important role in PCB manufacturing in the world. In recent years, the global status of PCB manufacturing has tremendous change, and most PCB manufacturing has transferred to Asia, especially China. China has become the main PCB supplier of the world. In the premise that electronic products tend to be more complex, the […]

How to solve the cycle watermarks around the plating hole?

How to solve the cycle watermarks around the plating hole? Phenomenon: Single side or double side, every hole, hole’s periphery, watermark, like any water remain after naturally dried. Possible reason and solution: Some people called this phenomenon fisheye, this phenomenon is in relation to the Chlorine content. If there is an absolute watermark, it may […]

Impedance matching in hi-tech PCB

Electronics engineers often encounter impedance matching problems. What the impedance matching is and why we do impedance matching? This article takes you to find out! In electronics, the blocking effect on the circuit is often referred to as impedance. Impedance’s unit is ohms, commonly referred to as Z, Z= R+i[ωL–1/(ωC)]. Impedance could adjust the load […]

The base material selection for High Speed PCB

One of our customers from Europe, they always design and purchase PCB from RCY PCB company. Last week I received an email from this customer, their engineer planed to design a High-speed project, but they don’t know how to choose the base material. This also no wonder, because they focus on some normal projects in […]

Why to do mixed surface treatment?

First of all, let’s take a look at this example of case,the context is that there was a project with BGA balls, but the BGA balls were peeled off in the thermal shock. We reviewed all production records and inspection results and excluded the possibility of everything except the reason of gold thickness.The good thickness […]

Castellated Hole PCB

The higher level of plated edges is the so-called half-hole technology for printed circuits, also named Castellations PCB or Castellated-Hole-PCB. Plated drills are cut in half on the outline of the PCB so that the shape appears like a stamp. Sounds simple but requires multiple additional processes and careful production planning during the CAM layout […]
