This embedded metal insert SMT soldering fixture integrates precision CNC machined aluminum inserts inside composite carrier base. The metal insert delivers outstanding heat conduction and precise window definition for selective SMT soldering.
This embedded metal insert SMT soldering fixture uses a composite outer frame, with an embedded aluminum alloy insert as the soldering window carrier. The metal insert is CNC milled to match complex PCB cutout shapes with ultra-tight tolerance. Aluminum material conducts heat evenly, reducing local temperature difference during wave soldering and improving soldering consistency. The composite outer frame isolates heat and protects the fixture base from thermal distortion. This design is ideal for PCBs with dense and irregular soldering areas. The metal insert can be replaced separately when worn, without replacing the whole fixture, lowering your long-term cost.

FAQ
Q1: What is the advantage of embedded aluminum insert compared to full synthetic stone jig?
A1: Aluminum insert has better thermal conductivity for consistent solder temperature, composite base keeps fixture flat.
Q2: Is the metal insert firmly bonded inside composite base during repeated heating?
A2: Special mechanical locking structure secures the insert, no loosening under continuous thermal cycling.
