Gould Electronics - Copper Products for Electronics

They develop and manufacture electro-deposited copper foils in various IPC grades and thicknesses up to 400┬Ám. These are used in high-end multilayer PCB. Electro-deposited copper foil forms the heart of many electronic gadgets and equipment we use today.

Gould Electronics - Copper Products for Electronics

GOULD Electronics is a global leader in the market for copper foil products and the partner of numerous leading copper clad manufacturers and board shops.

"Electrodeposited copper foil has been used for half a century as raw material in microelectronics."

GOULD Electronics History
  • First patent for electroplating copper foil issued to Edison - 1908
  • First production of ED copper foil in Eichstetten, Germany - 1963
Reverse Treated Copper Foil - Gould Electronics


Reverse treated copper foil is manufactured by applying copper nodularization, brass thermal barrier and passivation to the shiny smooth side of the foil rather than to the roughened matte side of the foil as is done when manufacturing conventional copper foil.

The treatment of RTC foils compared to standard foils provides faster, cleaner etching with more vertical sidewalls. Inner layer yields can be higher due to the cleaner etching and less undercutting of photo-resist.

Ametherm - Inrush Current Limiters and Thermistors

Since 1994, Ametherm has provided the most reliable and effective inrush current limiting solutions available.

Ametherm - Inrush Current Limiters and Thermistors

They have newly developed the MS 35 Series Inrush Current Limiters that are capable of handling up to 900 joules of energy and 50 amperes of steady state current. This will be a useful component to consider for power electronics engineers in the design of power supplies and inverters.

Protect An Inverter From Inrush Current

A common failure of inverters is overloading the inverter due to inrush current . This is due to the fact that most inverters are designed with a minimum amount of resistance to increase their efficiency and minimize losses due to heat.

Surge-Gard Inrush Current Limiters

NTC Thermistors - Negative Temperature Coefficient (NTC) thermistors are thermally sensitive semiconductor resistors which exhibit a decrease in resistance as absolute temperature increases.

SURGE-GARD Inrush current limiting devices have specially formulated metal oxide ceramic materials. These devices are capable of suppressing high inrush current surges.
