Do the different shapes and diameters snap domes can make into one metal dome array?

Wednesday, December 4th, 2013

Do the different shapes and sizes snap domes can make into one metal dome array? Answer is yes. For example, round and oblong snap domes, cross and triangle snap domes can make into one metal dome array.

Why do customers have this request?

1, Maybe customers’ pcb board design problems. For example, it can not use round snap dome for single pcb board, so that we can use oblong instead of.
2, Different click feeling required. Some require higher force, others require better click feeling;
3, Rubber key size. That require the different diameter of snap domes.

Although this metal dome array that can be made, the process of making is a bit more complicated, we need to make two assembly toolings and more time to assmble.So you can see the price should be higher. Therefore, we recommend: if you don’t have special requirements, please use one shape and diameter snap domes.

Metal dome and metal dome array is RoHS-compliant?

Monday, November 25th, 2013

Do our company produces metal dome and metal dome array is RoHS-compliant? Answer is yes, our products are not only sales in domestic, but also exported to Europe, America and many other foreign markets, so it must be with RoHS standard.

RoHS is the EU legislation to establish a mandatory standard, which stands for “Restriction of Hazardous Substances”. The standard was implemented by July 1, 2006, mainly for electrical and electronic products, materials and process standards, making it more conducive to human health and the environment. The purpose of this standard is to eliminate the lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers of six substances in electronic products.

If you need our products metal dome and metal dome array RoHS report, please feel free to contact our sales staff.

How to assemble metal dome on the dome array?

Tuesday, October 8th, 2013

How to assemble metal dome on the dome array? This may no contact with metal dome production people are unaware of.

Generally, there are two ways:

1, The metal dome array is formed by a metal dome assembly tooling, we shake up the metal domes onto the metal dome array. We make metal dome assembly tooling according to the metal dome shape. The material is aluminum plates, and each factory will make with a different thickness;

2, Through the tube to assemble. This method with small tolerances, faster, but the cost is relatively higher, it’s suitable for the production of large quantities.

In general, the first method are most used by facories, as it’s more simple, convenient and easy to operate. If you want to learn more about metal dome array production knowledge,we always welcome you to visit our company! ! !

Metal dome sheet with triangle shape production

Thursday, July 18th, 2013

This time let’s see the metal dome sheet with triangle shape production, we now talk here. Triangle metal dome sheet we generally divided into two types:

(1) Indefinite direction design, which requires the below pcb circuit board pad is circular design, so there is no direction will not affect the use of metal dome.

(2) With direction design, which requires the triangle metal dome are assembly with direction, to one certain direction. This is required with customers pcb circuit pad design. Similarly, you can look the picture below:

metal dome sheet with triangle shape direction

Two kinds of production methods we can make to meet the requirements of the guests, but relatively speaking, the second way of the production process a little bit harder, a little longer time to make.Because the assembly is not very convenient.
