RCY PCB – Company Profile

Shenzhen RenChuangYi Electronic Co., Ltd, also known as RCY PCB, was established in 2000. At first, it was a dedicated Tin-spraying factory and has a good reputation in the PCB industry in South China. In 2006, RCY invested a huge amount of money to introduce PCB full-process production. In just a few years, it has […]

A common question about prepreg thickness

Our customers could define the prepreg thickness and type in fabrication spec. If we do not have prepreg with the required thickness or types, we will make a very small change(by Engineering Query) to meet the layer stack-up and impedance requirements. Today our customer(Poland) told me that he is designing an 8 layer PCB that […]

How to choose material for layer stack-up of multilayer PCB?

When someone works on a multilayer PCB project, they have to calculate a stack-up for that PCB. Some of them may have some questions about how to choose material for layer stack-up of multilayer PCB. For example, using Isola 370HR for a 4L project assumed the finished board thickness is 1.6mm+/-10%, we can choose cores […]

The differrence between PCB and PCBA

PCB is the short name by Printed Circuit Board. PCB mechanically supports and electrically connects electronic components or electrical components using conductive tracks, pads, and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. (From Wikipedia) There are several types of PCBs such […]

The application of directional coupler

Directional coupler, a passive device used in radio technology.The application of directional coupler as below: 1) For power synthesis systems. In the multi-carrier frequency synthesis system, a directional coupler with 3dB is usually used. (generally called 3dB bridge) 2) For receiver’s anti-interference measurement or stray measurement. In the FR test and measurement system, if the […]

CAM software automation

Some of the industry-leading manufacturers are already enjoying the great benefits of process automation, such as production capacity improvement, data quality improvement, and training time shortening. Why do we need to automate? Why CAM can’t meet all needs of the automation function that we only need to push the right button to achieve auto-output? It’s […]

How to control the bow and twist in PCB manufacturing?

The IPC-6012 provides max. bow and twist not exceed 0.75% for the PCB from SMB to SMT. This article will show you how to control the bow and twist of PCB. Let’s find out the prevention methods of PCB bow and twist: Engineering design. The arrangement of PP between layers should correspond one-to-one; Core and […]
