Flexible PCB VS Rigidįlexible PCB have many similarities to rigid PCBs, see below: Some cost sensitive products that demand simplicity of installation and bendable conductors such as LED lighting use simplified and low cost flexible PCB. Generally, for products that involve sophisticated designs, or required to meet high performance standards, flexible PCBs are common place.
#Pcb manufacturer portable
Extensively used in medical industry, portable sensors and implants.Wearable electronics such as smart watches.Compact Designs and demanding applicationsĮlectronics products designers place rigid PCBs in consumer devices, such as: Consult with a manufacturer engineer that specialises in PCB design.
Additional rigid circuit boards with interconnectorsĪll things considered, flexible PCB often found be more cost-effective and in some cases the only suitable solution.Wiring harnesses, for low current applications.To get an accurate understanding of the total cost of alternative, examine your design and see whether flexible circuits may eliminate the need for some components, including It can also simplify assembly as for example in modern SLR Cameras and make compact packaging possible. Use of rigid of flexible circuit boards often reduces the size and weight, design dependant.ĭon’t dismiss flexible PCBs as too expensive at face value, consider total design cost as flex PCB replace not just just rigid PCB but also wiring harnesses and simplify connections. In general rule rigid PCB is less expensive than flexible circuits. When working out your device BOM budget, consider whether flexible PCB costs are worth it. Manufacturer is required to know number of bends the Flexible PCB will be subject to in it’s intended lifespan, this will help in selecting suitable materials and manufacturing techniques.
If your product requires to flex frequently without breaking, flexible PCB material your preferred choice over wiring harness. Going below the bend ratio will result in higher possibility of mechanical failure. This is expressed as a ratio of the thickness of the flexible PCB versus the bend radius. When working with flexible PCB manufacturer take into account the bend ratio. Because flexible PCBs are manufactured with polyimide, they’re also well suited for high-heat conditions. Reduced mass of the PCB dramatically improve it’s resilience towards vibration and G-force. DURABILITYĭoes your application require highly durable design?įlexible PCB manufacturers deliver durable solutions where vibration-related damage present an risk. If you’re thinking what type of PCB substrate is better choice for your design, consider these highlights below: 1. Selection Criteria: RIGID PCB or FLEXIBLE PCB
