Prototype Assembly

Our prototype runs are often a mix of large BGAs and tiny 0201 components, and we’ve had issues with other assembers on yield. PCBsync’s assembly team delivered a perfect first-run success. The board was pristine, the solder joints were impeccable under the microscope, and everything worked straight out of the box. Their attention to detail in the assembly process saved us weeks of debug time. They are now our go-to for critical prototype assembly.

Electronic Manufacturing

Scaling from hundreds to tens of thousands of units for our smart home device presented huge supply chain and manufacturing challenges. PCBsync’s full electronic manufacturing service was the solution. They didn’t just build the PCB; they managed the entire box-build, sourced all components (even during shortages), and implemented a rigorous quality control system that drastically reduced our field failure rate. They act as a true extension of our own production team.

Adhesiveless Flex PCB – Rolled Annealed RA Copper on PI, Dynamic Use

Product Details

The PCBSYNC adhesiveless flex PCB utilizes advanced material technology to eliminate acrylic or epoxy adhesive layers, bonding rolled annealed (RA) copper directly to the polyimide base film. This construction reduces total board thickness, enhances structural integrity, and drastically improves thermal dissipation. Designed for engineers and product developers requiring extreme reliability in dynamic use cases, this flexible circuit prevents the delamination and barrel-cracking risks often associated with traditional adhesive-based flex boards during repeated bending cycles.

Key Features of Adhesiveless Flex PCB Technology

Base Material: Adhesiveless Polyimide (PI) core for enhanced thermal resistance and dimensional stability.
Conductor Type: Rolled Annealed (RA) Copper (available in 1/3 oz, 1/2 oz, and 1 oz weights) for maximum dynamic flex life.
Thickness Efficiency: Elimination of adhesive layers reduces overall profile by up to 30%, optimizing tight z-axis spacing.
Thermal Performance: Maximum continuous operating temperature up to 150°C, suitable for high-reliability environments.
Standards Compliance: Manufactured and inspected to IPC-6013 Class 3 and IPC-A-600 standards.
Chemical Resistance: Superior resistance to harsh solvents, moisture, and outgassing.

Applications

Dynamic Flexing Joints: Ideal for print heads, disk drives, robotic arms, and gimbal systems.
Medical Electronics: Implantable devices, surgical imaging systems, and wearable patient monitors.
Aerospace & Defense: Satellite wiring harnesses, missile guidance systems, and dense avionics instrumentation.
Automotive Technology: Steering column sensors, battery management systems (BMS) for EVs, and infotainment displays.
