Benefits of Choosing Flexible PCBs for your Applications
Compared to other forms of PCBs, flexible PCBs can be manufactured with fewer interconnects, contact crimps, connectors and solder joints. With an unwavering commitment to quality, flex PCBs work best in GPS units, tablets, smart phones, cameras, and wearables, among others. A few amongst the several benefits of choosing these forms of PCBs include:

  • Small package size
  • High end performance in extreme temperatures
  • Improved resistance to vibrations and movement
  • High tensile strength
  • Lighter than a normal board
  • Higher current capacity than their rigid counterparts
  • Lower assembly and installation expenses
  • Mechanical and electrical repeatability
  • Superior resistance to radiation and chemicals
  • Installation flexibility
  • Increased reliability and durability

Applications of Flexible PCBs
Flexible printed circuit boards are the choice when reliability and maximum adaptability is utmost important and dynamic flexing of circuit is needed. They are largely incorporated in the making of pacemakers, cochlear implants, handheld monitors, aircraft missile-launch detectors, radio communication systems, control tower systems, signal processing systems, electronic control module, test equipment, electrical switches, among others.  Owing to their several proven features and benefits, the demand for flexible circuit boards has grown to unprecedented levels in industries such as:

  • Communications
  • Consumer Electronics
  • Automotive
  • Medical
  • Industrial
  • Aerospace
  • Military
  • Transportation

In harmony with the growing demands for flex PCBs, we being a prominent flexible PCB manufacturer, take on any flexible printed circuit board design challenge. With attentive customer support from design, through final production, we deliver quality products at competitive price.
