Flexible circuit boards

Flexible classification is very important to determine the type of flexible printed circuit board you are designing. Make sure you know what the standards and requirements are before you start designing. This will save you time and effort in the long run. Let's take a closer look at what the different categories and types of flexibility are and how they differ.

Elastic classification

The flexible aluminum pcb classified depends on the level of inspection and testing required and the performance requirements of the finished product. There are three different levels.

The first kind of

Apply to. General electronic products, including consumer products, some computers and computer peripherals, are suitable for applications where cosmetic defects are not important and the main requirement is to complete the function of the printed plate. Minimum inspection, testing and performance standards are required. Applications include disposable electronics.

The second type of

Apply to. Specialized service electronic products, including communications equipment, complex business machines, instruments requiring high performance and extended life, require uninterrupted service, but are not critical. Moderate inspection, testing, and performance standards are required. More expensive than first-tier products, the boards are used in cameras, smartphones and medical diagnostic devices.

Level 3

Apply to. High reliability electronic components include equipment and products where continuous performance is critical on demand. Equipment downtime cannot be tolerated and must be used when needed, such as in life support programs or flight control systems. This type of printing board is suitable for applications requiring a high level of assurance and service. The highest standards of inspection, testing and performance are required. These are the most expensive flexible panels. Applications include medical devices and military/aerospace electronics.

What are the types of flexible printed circuit boards?

The type of flexibility depends on the number, structure and material of the conductive layer, and whether there are electroplated through holes.

The IPC type 1

Single side flexible printed circuit board. This is the most common type of flexible circuit and is ideal for dynamic flexible applications. Contains a conductive layer. It can be found with or without reinforcement. SMT pads are accessible only on one side.

The IPC type 2

Double-sided flexible printed circuit board. It contains two conductive layers and has electroplated through holes. It can be found with or without reinforcement. The copper is bonded on both sides of the substrate and then drilled, electroplated, etched and insulated by a dielectric overlay on top and bottom.

The IPC type 3

Multilayer flexible printed circuit board. Containing three or more conductive layers with plated through holes. Plated through-holes are used to create conductive layers of interconnection. You can find one with or without reinforcement.

The IPC type 4

Multiple layers of a combination of rigid and flexible materials containing three or more conductive layers with electroplated through holes.

The IPC type 5

Flexible or rigid-flexible printed circuit board. Contains more than two conductive layers. No plating through hole.

Shenzhen Semshine Technology Co., Ltd. is a professional PCB supplier which is specialized in producing printed circuit board especially Alum base PCB since 2006. As a PCB supplier, Semshine is not only offering a one-stop service as PCB design, PCB production, and PCB assembly, but also taking great advantages on fast delivery time and competitive price with no quality compromise. There are two factories supporting us to be a better PCB supplier, which one is in charge of 1-4 layers PCB, another taking care of HDI PCB and multilayer PCB. Our PCBA service also have a good reputation from customer, because we source original components and make careful assembly for each board. Semshine is located in Shenzhen, China, near HONGKONG, in other words, the shipment is more efficient on time and cost for every customer. DHL, UPS, FedEx, Air, Sea shipping ways are available choices.

In years of development, Semshine owns more than 5000 sqm plant with over 10000 sqm per month production capability. We have the ability to manufacture 2-20 layers metal base (Alum, Cu, Iron), high Tg PCB etc. Recently we focus on Aluminum base PCB, especially our high heat conductive Aluminium PCB which is applied in cooling demand field, such as lighting -- street lights, lawn lights, fluorescent lights, stage lights -- electronic, mechanical, telecommunications, automotive etc.

We acquired ISO9001:2000, UL and RoHS approval for further development. Until now, we have built up good reputation among domestic and foreign customers, and our business extends far into Europe, America, Southeast Asia, and the Middle East etc. Every year, we join in different electronics exhibitions as products promotion such as HK Fair, Productronica Munich，Productronica IndiaINTERNEPCON JAPAN Moscow Crocup fair etc.

You are welcome to visit our factory, we are looking forward to establishing a long-term cooperative relationship with you.
