Specializing in Flex & Rigid-Flex PCB Assembly Services
Topline Circuit handles complex PCB projects from layout and fabrication through assembly. Our engineering and production teams work together to support each stage of the project under one roof. This integrated approach improves communication, simplifies production control, and reduces handoff risks.
We also understand the special handling required for flex and rigid-flex PCB assembly. Proper process control helps reduce the risk of damage and delamination during assembly. By combining PCB fabrication and assembly in one facility, we shorten the supply chain and help reduce delays, errors, and coordination problems.
PCB Assembly Capabilities
Buried resistors are embedded within the PCB layers. They save surface space and reduce the need for surface-mounted resistors without significantly increasing the finished board thickness.
During fabrication, the resistive material is laminated to a dielectric layer and subtractively etched to form planar resistors. The completed resistor layer is then laminated into the PCB stack-up.
Buried resistance can improve impedance matching, reduce noise and crosstalk, and support stable circuit performance. However, tight resistance tolerances can be difficult to maintain during etching and lamination. Processing conditions may also change the final resistor value.
