Before the small series in the company's website has made a certain introduction to conductive foam, but very customers and friends reflect that we have not made a detailed introduction to conductive foam before, hope to see a more detailed introduction to conductive foam. Such a small series today combined with their own sophisticated theory to begin to conductive foam to a comprehensive introduction.

First of all, let's talk about the birth history of this magical material conductive foam.

Conductive foam entered the public eye at the end of the last century, the function is to shield the radio wave interference between the components on the circuit board, the first method is the metal shielding method, which does have a certain shielding ability in the early stage. However, with the increasing demand for precision of electronic components and the increasing popularity of small electronic products, the initial metal shielding will be greatly reduced in the shielding effect, in addition to the internal structure of the product will take up a lot of space, and the final manufacturing cost of shaped metal is also extremely high. What to do? So conductive foam this product came into being.

Conductive foam, consisting of conductive cloth wrapped in conductive foam material, conductive cloth and conductive foam coated with special conductive adhesive, conductive cloth coated with fixed conductive adhesive, conductive adhesive in the initial viscosity, holding force can be freely set according to product requirements. There are a variety of conductive foam products on the market, and there are many model parameters, which are composed of such basic structures. It can be roughly understood that the conductive cloth plus conductive foam and conductive adhesive is equal to the finished conductive foam, of course, the conductive foam rubber surface will be affixed with a layer of special release paper as the conductive cloth. In addition, if the conductive foam is subdivided, the conductive PE we are familiar with on the market is also a kind of conductive foam, corresponding to different customer requirements and product materials, there will be different product colors as a distinction.

What kind of use does conductive foam have?

In terms of use, the range of conductive foam can be applied is too large, so we will not give one example here. The conductive foam products supplied by Yajin are mostly used in precision electronic products such as mobile phones, car navigation, tablet computers, laptops, etc. Most of the functions are used for electromagnetic shielding at the interface. In addition, conductive foam has excellent conductive effect and good corrosion resistance effect, strong plasticity, can be applied to different electronic products from different angles, and the cost will be much more affordable than metal shielding, this series of product advantages, making conductive foam in many product areas have a good performance.

When you understand and begin to use conductive foam, will you ask, this product is so tough, can not be piled up at will? The answer, naturally, is "no."

We should remind you that the storage of conductive foam has strict requirements for the environment. First of all, conductive foam can not be stacked at will in terms of the physical environment. Once conductive foam is squeezed for a long time, the basic thickness of the foam will be reduced and the performance of the foam will be directly affected. Secondly, in terms of temperature control, because the glue between the conductive foam and the conductive cloth substrate and the glue between the conductive cloth and the veneer, the temperature has certain storage requirements, and the new product needs to be cooked. Finally, conductive foam is stored in the above way, whether everything is safe? Naturally not, conductive foam also has a warranty date, as for the date of aging, you need to consult the corresponding supplier to understand.
