Blade length is the step where rubber squeegee orders most often go wrong. A blade that is too short leaves poor print quality along both PCB edges; one that is too long may hit the machine rails or the board fixtures. This page is a quick length lookup by machine type for compatible rubber squeegee blades used on GKG, SPG, MPM, SPD and other printer brands, to help buyers match the right size and order fewer wrong parts. Sold as single blades.
How to choose the length: the squeegee is usually the PCB width + 20–40 mm (10–20 mm spare on each side), so pressure is even across the whole board. Large main boards (400 mm and wider) usually take 450–550 mm blades; standard PCBs (200–350 mm wide) take 250–400 mm blades; small SIM card or module boards can use 150–200 mm blades. If you replace the squeegee holder at the same time, also check its hole pitch and angle (45° / 60°).
Trademarks: GKG, SPG, MPM and SPD are trademarks or model names of their owners, used here only to identify compatible machines. JIAHON is not the authorized distributor of these brands in Taiwan.

|---|---|---|
| ≤ 150 mm | 150 mm | GKG and other printer brands (small-board models) |
| 150–180 mm | 200 mm | GKG and other printer brands |
| 180–230 mm | 250 mm | GKG / SPG and other printer brands |
| 230–260 mm | 280 mm | GKG and other printer brands |
| 260–280 mm | 300 mm | GKG / MPM and other printer brands |
| 300–320 mm | 350 mm | GKG / SPD / SPG and other printer brands |
| 360–380 mm | 400 mm | MPM / GKG / SPD / SPG |
| 400–420 mm | 450 mm | GKG and other printer brands |
| 460–480 mm | 500 mm | GKG and other printer brands |
| 510 mm and over | 550 mm | GKG / SPD / SPG and other printer brands |
Note: this table is a general guide; the final length must suit your machine’s rail width. When you ask, please give the PCB size and machine model and we will help confirm the right length.
