FR4 94V0 Printed Circuit Board PCB

FR4 94V0 Printed Circuit Board PCB

FR4 is the most common used material for PCB.FR-4 is a code name for a grade of flame-resistant material. It means a material specification that the resin material must extinguish itself in the burning state. It is not a material name but a material grade. And there are many types of FR-4 grade materials used in panels, but most of them are composite materials made of so-called Tera-Function epoxy resin plus filler and glass fiber. When first stepping into this field XD gained lots of experiences of FR4 94V0 Printed Circuit Board PCB.

1.How do we keep our prices low?

We are PCB manufacturer and also have relationships with a large number of component manufacturers and can find the best source of material to consistently save your cost, meet your development schedule, fulfill your prototyping or mass production needs.


2.What is Test NRE?


3.The Test NRE is a one-time "non recurring expense" for electrical test. This charge is optional but when paid, all circuit boards will be tested each and every time that part number and revision is ordered without additional charge.


4.When do you pay a tooling NRE fee for my printed circuit board?

 You will only pay a Tooling charge if you go directly to Production (Custom Spec) without having ordered a Prototype(Standard Spec) as a first step. We do not charge Tooling for Prototype (Standard Spec) and neither do we charge Tooling if the prototype (Standard Spec) is reordered for Production (Standard Spec).


5.If you only have a minor change in my design, do we charge Tooling NRE?

When you make any change to your printed circuit board, we assign it completely new tooling. This helps prevent old artwork or cnc programming from being used. Even a minor change will require the same process as new files, so a tooling charge may apply. Please contact your salesperson for details.


6.Are your "Prototype" PCBs processed differently from your Custom Spec PCBs?

No. Our Standard Spec ("prototype") use the same premier manufacturing processes as our production(Custom Spec) circuit boards.


7.To what acceptability standards do we build?

IPC A600 Class 2 through IPC 6012 Class 3A


8.Where should you send your files to get a printed circuit board quote or place an order?

You can simply send us an inquiry via Alibaba site. Very soon our sales person will contact you for your inquiry/files. Or you can send your inquiry/files to our email address


9.How fast can you get a quote after submitting an inquiry?

We will on receipt of your file evaluate in 6 hours for standard spec PCB. But if PCB special, evaluation will be longer. Please note that the following detail will speed up evaluation:
