Double sided flexible PCB board with plated through holes
$23.80
Two conductive layers are present on both sides of the flexible substrate of double sided flexible PCB board. Plated through holes are used to provide the connection between the two copper layers. Double sided flex PCB can realize complex and compact which is suitable for applications that require dynamic movement or space constraints.

Questions & Answers
1.What are your available logistics options?
Our shipping methods include air freight, express delivery, and sea transport, depending on your urgency and shipping requirements.
2.Which payment methods are available?
You can choose from multiple payment options like T/T, West Union, Money Gram, L/C, and PayPal (for samples). Please speak with our sales team for more information.
3.What common materials can be used as stiffeners for double sided flex PCB?
Stiffeners can reinforce critical areas of the flex circuit board and can be made from polyimide, aluminum sheet, steel sheet, FR-4, etc.
4.Why is the minimum bend radius important for flexible PCBs?
The minimum bend radius determines the smallest angle at which a double sided flexible PCB board can be bent without damaging the traces, materials, or interconnects. Exceeding this limit may cause copper trace breakage, delamination between layers, and shortened service life.
5.What are the types of insulation protection for double-sided flexible PCBs?
Double sided flexible PCB board can use several methods for insulation, including insulation film, light imaging coverlay, photographic solder mask, silkscreen solder mask, etc.
