"Everything we build starts with design engineering. CECL manufactured boards for one of our products. It went perfectly – a real success.It is really an high quality service they have provided to us!"

By Nile Smith from Sinotech Inc.

“We had several very old device with obsolete boards need to be replaced –through CECL professional service.We got what we needed, and we’ve been using the results of the work without any problem till now.”

By Richard Anderson from TWP system Inc.

"Guys from CECL manufacture PCBs we use in one of our products, a clinometer and we’ve never had a problem with anything. The boards come in, they work. And, their team is very responsive."

By Ken Camerlo from Hi-END ADV Inc.

Reverse Engineering Inverter System PCB

Reverse Engineering Inverter System PCB

Inverter system PCBs are becoming more compact and complex while requiring greater power density. This challenge can be met by adopting a Fairchild Smart Power Module. Reverse Engineering Inverter System PCB layout design is very crucial in improving reliability, performance, and manufacturability while minimizing noise. This application note describes several considerations and guidelines for PCB layout design.

Below Figure shows the overall guidance for PCB layout design, labeled from number 1 to 12 in order of importance.

CONSIDERATION:

Parasitic Inductance, Resistance, and Capacitance

Voltage Spikes from di/dt through the Parasitic Inductance

Route of Power Ground, Signal Ground Layout

Placement of Passive Components
