Project Description

Project Background:

At the end of 2019, we received inquiries from customers in the United States. Customers need PCBs with high TG and high quality and used in industrial control high-end instruments. Therefore, when selecting a panel, you need to use high-quality PCB materials. The purpose is to provide high-quality products to meet design requirements such as height, reducing crosstalk, improving signal integrity, and improving power consumption. The number of PCB layers usually depends on the power distribution and signal routing density. We provide customers with three different types of circuit boards and make samples according to their requirements. The needs of customers were finally met.

PCB description:

In today’s products, the typical application of electronic instruments is within 1GHz. There are many vendors and materials that provide excellent signal characteristics in terms of impedance control and insertion loss. Impedance control is critical for memory and I / O interfaces. Insertion loss determines the signal integrity of the design, so we provide customers with the following three circuit boards.

Rogers RO4000

Features of Rogers RO4000. This series of high-frequency circuit materials are glass-reinforced hydrocarbon / ceramic laminates (non-PTFE) designed for high-volume commercial applications sensitive to performance. RO4000 laminates are designed to provide excellent high-frequency Performance and low cost circuit manufacturing. Therefore, low-loss materials can be manufactured using standard epoxy / glass (FR4) processes at competitive prices.

The characteristics of Rogers RO4000, this material has the performance required by RF microwave circuit designers. Stable electrical performance under ambient conditions makes repeatable designs of filters, matching networks and controlled impedance transmission lines possible. The low dielectric constant makes the RO4000 series materials useful in many applications where higher operating frequencies limit the use of conventional circuit board laminates.

Test Method:

As developer and circuit design engineer; the best test method for PCB is real-time PCB application signal test and measurements, measuring signal losses, cross-talk, power trace impedance.
Using electronic test and measurement tools such as power supply, function generator, spectrum analyzer and network analyzer, one can determine quality of PCB work.

Customer Feedback

The most important cooperation key with any PCB vendor is quality of their product followed by delivery schedule and cost. The quality would be the primary concern as lots of work will go into design and development of any product. Ensuring quality of product would be key success factor for any design.

 

After the customer received the plates, they gave us a high quality evaluation.

Why do you continue to cooperate with us?

Per previous PCB design cycle, identified the improved product quality in comparison to other PCB fab companies. Additionally – Your company’s skilled engineering team were able to identify PCB issues prior to PCB build, saving cost and improving PCB design quality.
Friendly sales team – managing PCB work from start of any project to delivery is vital important. It has been pleasure to work with Ms. Frances on several projects and looking forward to work on upcoming project with your company’s team.
