Before we talk about the impedance control, let’s see how Wikipedia explains about this: Impedance control is an approach to the control of dynamic interaction between a manipulator and its environmen... (See More)
Regardless of the inherent quality of the PCB, the surface is similar. It is through the surface that we see the differences that are critical to the durability and functionality of the PCB throughout... (See More)
About the Chip Capacitor
For the Chip capacitor, it is coated with a metal layer on the porcelain tube, and then forming two poles inside and outside. Because the tube is empty, so it called with ch... (See More)
Electric capacity is made up by the two metal pole and insulating media in the middle.
Due to the different insulation materials, the composition of capacitors is also different:
According to t... (See More)
Capacitors play an important role in high-speed PCB design and are the most used devices on PCB boards.Now we mainly introduce the filter capacitor.
In simple, in the filter circuit, filter ca... (See More)
Capacitors play an important role in high-speed PCB design and are often the most used devices on PCB boards. Capacitors of different applications play a different role in the PCB board, and usually b... (See More)
We are having some problems with "drawbridging" on 0805 film capacitors. We have already reduced the pad width from .050" to .040" based on input from vendor. Defects appear to be random as far as loc... (See More)
We manufacture a mixed technology board, that uses a through hole "mini cap" with a 2.5 mm lead span. We have had several failures caused by solder wicking up through the plated through hole pcb and t... (See More)
