Key Differences:
Framed Screen Printing Table: Features a rigid frame, with the screen fixed to the frame. Offers high stability and precision, but is more expensive and less flexible.
Frameless Screen Printing Table: Lacks a fixed frame; the screen requires a tensioning system. Lower cost and easier storage, but precision depends on the tensioning process, and durability is weaker.
Selection Scenarios:
Choose framed:

For large-scale production, automated production lines, and complex PCBs (fine-pitch components), prioritize its stability and precision.
Choose frameless:

For prototyping/small-batch production, limited budgets, and frequent design changes, utilize its low cost and flexibility.

Both are suitable for small-batch printing and customers with limited budgets, and are an important part of the SMT production line.
