Assembly Capabilities for Flex & Rigid-Flex PCBs<\/h2>\n\n\n\n
Assembly Capability<\/th>Description & Key Applications<\/th><\/tr><\/thead>
Surface Mount Technology (SMT)<\/strong><\/td>Components are mounted directly onto the PCB surface. It is the standard method for high-density, modern electronic assemblies.<\/td><\/tr>
Through-Hole Technology (THT)<\/strong><\/td>Component pins are inserted into drilled holes and soldered. It provides strong mechanical bonds, often used in military, aerospace, and heavy-power applications.<\/td><\/tr>
Flip Chip<\/strong><\/td>The silicon chip is inverted and connected directly to the substrate bumps. It offers shorter electrical paths and is used in high-performance, compact designs.<\/td><\/tr>
Selective Soldering<\/strong><\/td>A programmable machine solders specific through-hole components by controlling pre-heat, flux, and solder time, protecting surrounding heat-sensitive parts.<\/td><\/tr>
Press Fit<\/strong><\/td>Creates a gas-tight connection between the PCB and plated through-hole without soldering. Ideal for high-current connectors and aerospace applications.<\/td><\/tr>
Automatic Optical Inspection (AOI)<\/strong><\/td>Uses high-resolution cameras to detect component presence, orientation, solder joint quality, and alignment defects during or after the reflow process.<\/td><\/tr>
X-Ray Inspection<\/strong><\/td>Verifies hidden solder joints beneath components like BGAs and QFNs, ensuring internal structural integrity and precise alignment.<\/td><\/tr>
In-Circuit Testing (ICT)<\/strong><\/td>Uses a custom fixture to electrically test individual component values, circuit continuity, and functionality on populated boards in mass production.<\/td><\/tr>
Flying Probe Testing<\/strong><\/td>Uses movable probes to check circuit continuity and opens\/shorts without a custom fixture. Highly cost-effective for prototype and low-volume runs.<\/td><\/tr>
Conformal Coating<\/strong><\/td>Applies a protective chemical layer (e.g., acrylic, silicone) to the assembled PCB to shield against moisture, dust, chemicals, and extreme environments.<\/td><\/tr>
Mechanical Assembly \/ Box Build<\/strong><\/td>Integrates populated PCBs into final enclosures with cables, displays, and mechanical parts, delivering a complete, ready-to-use electronic product.<\/td><\/tr>
Reballing<\/strong><\/td>The process of replacing or renewing the solder balls on BGA components, enabling the repair, testing, or reuse of high-value integrated circuits.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
