This 4-up quad cavity SMT wave soldering fixture is built with yellow fiberglass edge guard and four independent PCB cavities. It can process four PCBs in one single wave soldering pass to boost line throughput.

This 4-up quad cavity SMT wave soldering fixture adopts high-temperature resistant composite base plate paired with yellow fiberglass reinforced border, which protects the carrier from abrasion on SMT conveyor rails. Four separate custom cavities are arranged symmetrically on the plate, allowing four identical PCBs to be loaded and soldered in one cycle. Adjustable positioning clips and spring locators are mounted around each cavity to hold PCB flat and prevent shifting during tin wave contact. The precision CNC cutouts cover sensitive top-side SMD components and only expose the required through-hole solder pads. The composite material maintains stable dimension under repeated thermal shock, minimizing thermal deformation after long production runs. This 4-up design balances production efficiency and fixture size, ideal for mid to high volume SMT production with standard PCB dimensions.

FAQ
Q1: Can the 4 cavities be customized to hold different PCB designs in one fixture?
A1: Yes, we can machine mixed cavities if you need to run multiple PCB variants in one soldering cycle.
Q2: Does the 4-up fixture have higher thermal deformation risk compared to 2-up models?
A2: The fiberglass reinforced frame improves rigidity to control warpage, keeping stable performance in continuous production.
