Why need Through-hole etch-back? As we know there are more and more smart device, and more smaller. In other hand, require high end PCB board. And more of the time those devices require flex PCB or rigid-flex PCB. Some of China flex-rigid PCB factories have developed through-hole etch-back technology to meet high end requirement. Top […]

The biggest difference of double sided flexible PCB As we know more of a PCB board definition by its layers, especially copper layer number. Yes, Double sided flexible PCB has two copper plane layers. And those two copper plane layers always printed line in flexible PCB. That’s the reason why one of the copper plane […]

There were two types of single-sided flexible circuit constructions. The first one is the copper can be bonded directly to the dielectric. And there was no any adhesive material.That the reason why all Flexible PCB have good bending ability. The second one is very differ with the first type constructions of single-sided flexible circuits. It […]

If you have read our flexible priented circuit board articles before, you may know most of conents are from customers. But this article is differ, we will from designers and engineers mind. To know How understand flexible PCB in FPC designer and engineer mind. We have chatted with most of our friends, most of them […]

If you read news from internet, will always read some of PCB assembly labor issues. Especially in some thinnest rigid PCB plants, have a difficult time filling open positions. In fact, those news has reported years, but also none solution.

It’s ture that there were fewer young adults go to manufacturing than decades. We discuss manufacturing lack labor want to let more guys know this. Due to everything we use during our daily lives have been manufactured in one way or another. In this words, like semi rigid PCB factory lack labor is relate to […]

There were some customers ask the extra thin rigid PCB can we do in their first question. Author have several answers for this question. First situation, I will ask a customer what the layer they want to? Due to differing layer rigid PCB have differing thickness. For most 1 or 2 layer conventional Fr4 rigid […]
The Flexi rigid PCB UK topic is very big, and related to many flexible PCB factors. This post we will focus on automotive flexible, rigid PCB in UK discussion. We have discussed flexible PCB use in medical application. We are going to discuss another flexible PCB application. As we know the car become more modern […]
