What you need to know about foil tapes?
Foil adhesive tapes are an extremely versatile and durable solution for rugged and harsh applications. Reliable adhesion, good thermal/electrical conductivity, and resistances to chemicals, humidity, and UV radiation make foil tape one of the most popular options for military, aerospace, and indu...Read more -
Types of PCB Copper Foil for High-Frequency Design
The PCB materials industry has spent significant amounts of time developing materials that provide lowest possible signal loss. For high speed and high frequency designs, losses will limit signal propagation distance and distort signals, and it will create an impedance deviation that can be seen ...Read more -
What is Copper Foil Used for PCB Manufacturing Process?
Copper foil has low rate of surface oxygen and can be attached with a variety of different substrates, such as metal, insulating materials. And copper foil is mainly applied in electromagnetic shielding and antistatic. To place the conductive copper foil on the substrate surface and combined with...Read more -
The Difference between RA Copper and ED Copper
We are often asked about flexibility. Of course, why else would you require a “flex” board? “Will the flex board crack if use ED copper on it?’’ Within this article we would like to investigate two different materials (ED-Electrodeposited and RA-rolled-annealed) and observe their impact on circui...Read more -
Copper Foil Used in Printed Circuit Board
Copper foil, a kind of negative electrolytic material, is deposited on base layer of PCB to form continuous metal foil and it is also named as the conductor of PCB. It is easily bonded to the insulating layer and able to be printed with a protective layer and form circuit pattern after etching. ...Read more -
Why is Copper Foil used in PCB Manufacturing?
Printed circuit boards are necessary components of most electrical devices. Today’s PCBs have several layers to them: the substrate, traces, solder mask, and silkscreen. One of the most important materials on a PCB is copper, and there are several reasons why copper is used instead of other alloy...Read more -

How to produce ED copper foil?
Classification of ED copper foil: 1. According to the performance, ED copper foil can be divided into four types: STD, HD, HTE and ANN 2. According to the surface points, ED copper foil can be divided into four types: no surface treatment and no prevent rust, surface treatment of anti-corrosion,...Read more -
Do You Know That Copper Foil Can Also Make Beautiful Works Of Art?
This technique involves tracing or drawing a pattern onto a sheet of copper foil. Once the copper foil is affixed to the glass, the pattern is cut out with an exacto knife. The pattern is then burnished down to stop the edges from lifting. Solder is applied directly to the copper foil sheet, taki...Read more -
Copper kills corona virus. Is this true?
In China, it was called “qi,” the symbol for health. In Egypt it was called “ankh,” the symbol for eternal life. For the Phoenicians, the reference was synonymous with Aphrodite—the goddess of love and beauty. These ancient civilizations were referring to copper, a material that cultures across t...Read more
