Definition of Lead Free

Tuesday, September 19th, 2006

For several years, the industry has been working towards eliminating lead in electronics by July 1, 2006, as required under the European Union’s Restriction of Hazardous Substances (RoHS) Directive. The RoHS Directive stands for “the Restriction Of certain Hazardous Substances in electrical and electronic equipment”. But complying with RoHS is actually much more complicated, as companies are finding out. There are a lot of issues, and it’s a challenge keeping track of them all, let alone implementing industry wide and company-specific solutions. (more…)

ESD and EMC

Wednesday, September 13th, 2006

As we mention in our products metal dome arrays - EMI printing, on top of the Mayler which carries metal dome contacts, silver paste or silver carbon paste is printed as ESD (Electrostatic Discharge Control). In fact, not only we use ESD in metal dome arrays, but also other products need it, it’s such a important accessories that it can be found in most cases of all high precision end products, such as the Cell Phones, electronic transmitters, and so on. Now let’s take a brief glance at the following words to unveil it 

ESD

(Electrostatic Discharge) is the term used to describe the sensitivity of electronics components to static electrical charges. (more…)

About Stainless Steel - Raw Material of Metal Dome (2)

 For the previous article, please view http://www.metal-domes.com/blog/2006/09/08/stainless-steel-material-of-metal-dome-1 

4) Families of stainless steels

There are several families of stainless steel: FERRITIC, MARTENSITIC, AUSTENITIC and DUPLEX. These names are derived from the crystal structure of the steels, which governs their metallurgical behaviour.

FERRITIC stainless steels are magnetic, have a low carbon content and contain chromium as the main alloying element, typically between 13% and 17%.They are not hardenable by heat treatment.

About Stainless Steel - Raw Material of Metal Dome (1)

Friday, September 8th, 2006

As you know, the raw material of metal domes (or named snap domes) is stainless steel. (Sometimes the phosphor bronze are used, but much seldom). The quality of material will affect the quality of finished metal domes, so we must be much careful in purchasing stainless steel. Now let’s take a brief glance at the information about stainless steel, hope it’ll be useful for you to understand it and helpful in others. You are also welcomed to provie the supplements about it. Leave your response or send us an email.
