Industrial applications

There are many extreme problems in industrial manufacturing, and rigid-flex PCBs are the experts in this area. The circuits and devices used for power transmissions are created through use of heavy equipment, so their movement from one place is another is not easy and increases damage changes of them since it is heavyweight. Since these modules require both heavy lifting capacity and flexible and precise control, ordering a turnkey rigid-flex PCB assembly service is the only option.

More serious is the use of high temperature equipment in the industry, such as electric furnaces, melting furnaces, heaters, etc. Although these equipments are almost essential, they are a nightmare for PCB manufacturers. Faced with this extreme environment, your options become very limited, such as rigid ПЕЧАТНАЯ ПЛАТА IMS, or rigid-flex board, which can better solve the problem of heat dissipation and high temperature.

Use in Online Business

Is it necessary to purchase a rigid-flex PCB?​

The rigid-flex PCB board is a hybrid board made through a mixture of flexible and rigid PCB boards. For the creation of these boards, there is the use of one or more than one rigid boards combined to flexible boards. These boards are considered the replacement for жесткая печатная плата. These boards have features of flexible and rigid boards in one unit. Many rigid-flexible PCBs come in a structure that has a multilayer of flexible substrates combined with a rigid substrate. Flexible parts of boards designed in curvature structure according to requirements of projects. Although this kind of rigid-flexible circuit board has many advantages, its price has discouraged many electronic manufacturers. Is it necessary to choose rigid-flexible PCBA among many different типы ПХД?
