SMT Assembly

Surface mount technology (SMT) is a method for constructing electronic circuits in which the components are mounted directly onto the surface of flex PCB boards. This technique allows for smaller, more compact, and higher-performance electronic assemblies compared to Through-Hole Technology (THT).

THT Assembly

Through-hole technology (THT) Assembly is a method of constructing electronic circuits in which the components are mounted by inserting their leads through holes drilled in FPCB and soldering them in place on the opposite side.

SMT & THT Mix Assembly

Mixed Assembly is a process that combines both Surface Mount Technology and Through-Hole Technology in the assembly of flexible printed circuit board. This method is advantageous for complex circuit boards requiring a variety of components, utilizing the efficiencies of SMT and the strong mechanical bonds of THT.

Everything under one roof – component sourcing, FPCB assembly, testing, and final delivery.
Better pricing – our supplier network helps cut costs without cutting corners.
No delays – verified parts and smooth logistics keep your schedule on track.
Scalable support – whether you need a small prototype run or mass production.

Instead of juggling multiple vendors, you get a single partner who manages the details and keeps things moving. That way, you can focus on building products that reach the market faster.

FPCB Assembly Process

Flexible PCB assembly follows a step-by-step process to ensure reliability and high performance. From incoming material inspection, include careful checks of bare flex circuit boards and electronic components. Next, paste the solder onto the pads, and using automated pick-and-place machines to place the components . and then go through reflow soldering to secure the parts. Afterward, automated optical inspection (AOI) is carried out to detect any defects. If the design includes through-hole parts, they are inserted and soldered either by wave soldering or manual soldering. Once assembled, the boards are tested for electrical performance, followed by final inspection and cleaning. Finally, the completed flexible PCB assemblies are packaged and shipped to customers.

Mastering FPCB, Flex PCB Assembly:
Overcoming Technical Challenges with Flex Plus

Bending and Flexibility Optimization

Ensuring the FPCB's bending capability without compromising electrical performance can be challenging. At Flex Plus, we employ advanced material selection and design optimization techniques. By utilizing flexible substrates with suitable reinforcement layers and controlled bending radii, we achieve outstanding flexibility while maintaining reliable electrical connections.

Moisture Absorption Prevention

FPCBs' susceptibility to moisture absorption during transportation and storage can lead to defects like delamination and blistering during reflow soldering. To counter this, we implement a precise pre-baking process, removing moisture before assembly. This proactive approach ensures the long-term reliability and performance of our FPCB.

High-Quality Soldering

Maintaining reliable solder joints on flexible substrates is critical for long-term performance, especially during repeated flexing. Flex Plus utilizes high-quality solder paste, precise reflow soldering profiles, and proper component trimming to ensure robust and durable solder connections, enhancing the overall reliability of our Flex PCB assembly.

Precise Component Mounting and Alignment

The lack of rigidity in FPCB boards can challenge precise component placement and alignment. Flex Plus employs state-of-the-art pick-and-place machines with optical positioning systems. Additionally, our specialized carrier fixtures facilitate accurate component mounting on the flexible substrate, ensuring optimal electrical performance.

Comprehensive Inspection and Testing

Inspecting and testing FPCB can be more challenging than rigid PCBs due to their non-planar surfaces. We have developed specialized ICT and FCT fixtures to perform thorough inspections. Our visual inspection with magnification and implementation of advanced AOI systems ensure early detection and correction of any defects, guaranteeing the highest quality end products.
