Copper Foil Shortage

A shortage of copper and copper foil for use by the printed circuit board (PCB) industry is likely to send prices higher according to Raymond Goh, COO of Elmatica AS (Oslo, Norway), a PCB broker.

Goh said that the global output of copper is not increasing while demand for copper in lithium batteries for automotive applications is and that as a result a current shortage of copper foil will persist. On top of this China is planning to ban the importation of electronic waste, a significant source of recycled copper, Goh said.

Although others will undoubtedly continue to recycle electronic waste Chinas exit would represent a disruption to the process creating a temporary decrease in copper supply.

One alternative to using copper foil for shielding is Tinplate which happens to be solder-able like copper is, Tinplate is used as shielding material in a lot of electronic devices such as DVD players, TVs, Computers and etc.

Aluminium works well too. I shielded the cavity in my cheap Ashton bass guitar with alfoil - just glued it in - made a huge difference to the hum.

Squier use conductive paint, or at least that is what is in my CV Thinline
