LeTkingok 150x130MM PCB Universal Test Stand
Product name: PCB universal test frame. Material: Grade A Bakelite + Acrylic. Supports PCB size: 150x130MM. This compact fixture provides a stable base for small boards, facilitating quick setup and repeatable alignment during testing cycles. The combination of Bakelite and acrylic offers rigid support while keeping the fixture relatively lightweight for repeated repositioning during prototyping projects.
LeTkingok PCB Universal Test Stand 180x160MM
Product name: PCB universal test frame. Material: Grade A Bakelite + Acrylic. Supports PCB size: 180x160MM. The larger footprint expands the fixture’s capacity for mid-size boards, supporting more complex assemblies during functional testing or ICT processes, with a design that preserves stable clamping without masking sensitive traces.
Aitoserlea Multifunction Test Stand 270x210MM
Product name: Multifunction PCB Jig Functional Test Stand. Material: A-grade acrylic plate. Features: Special quick clips for fast positioning and installation; bearing seat with positioning bumps for precise replacement; safe rounded edges. This fixture supports efficient workflow for ICT and functional testing with fast setup and replacement workflows for boards around 270x210MM.
Aitoserlea Multifunction Test Stand 120x90MM
Product name: Multifunction PCB Jig Functional Test Stand. Material: A-grade acrylic plate. Features: Quick clips for fast positioning; positioning bumps for easy, precise replacement; rounded and beveled corners for safe handling. Suitable for compact PCBs and quick test iterations in tight workspaces.
Toplionace Universal Test Frame 240-180-60
Product name: Universal Test Frame PCB Testing Jig PCBA Test Fixture Tool. Material: Bakelite. Features: The cover can be opened to facilitate welding lines; replaceable A, B, C boards for easy replacement; adjustable distance between B and C boards. This design supports flexible configurations and easier access to the board during testing and assembly workflows, especially for mid-to-large PCBs.
Buying Guide: Key Purchase Considerations
- Board size compatibility: Confirm the maximum supported PCB dimensions and whether the fixture accommodates your most common sizes. Some fixtures excel for small boards (around 100–150 mm), while others handle larger panels (up to 270 mm and beyond).
- Material and durability: Bakelite frames with acrylic inserts provide rigidity and light weight. Look for rounded edges and smooth finishes to reduce risk of board damage or user injury during handling.
- Clamping and positioning: Quick clips, positioning bumps, and adjustable board spacing help reduce cycle times and improve repeatability across tests and prototypes.
- Access and workflow: Open covers or easy access to welding lines can be critical for certain PCB assembly tests. Consider whether you need full or partial cover access for your process.
- Upgrade and replacement options: Check if boards or inserts (A/B/C boards) are easily replaceable to minimize downtime when boards change during testing.
- Size vs. workspace: Larger fixtures offer more capacity but require more bench space. Balance fixture footprint with your available lab or workshop area.
- Compatibility with test equipment: Ensure the fixture design works with your ICT, functional test, or jig-based testing tools, including alignment with test probes and fixtures.
- Safety considerations: Look for smooth edges, secure fasteners, and no sharp corners. A dedicated jig reduces risk during repeated clamping and unclamping cycles.
In selecting a testing jig for PCBs, prioritize reliability, ease of use, and adaptability to your testing pipeline. Whether you need compact frames for small boards or larger fixtures for mid-size panels, the options above aim to deliver stable positioning, quick setup, and safer handling during PCBA testing and prototyping cycles.
