LS-77A Main Features
  • Fine pattern printing is possible. The squeegee head’s linear axis receiver uses a special guide to minimize vibration and to greatly improve uniform speed. This allows fine pattern printing with three lines between pins.
  • Improved stability for high-speeds. With the frame’s lighter weight and high rigidity, the stabilized frame can be raised and lowered by motor. The motor can drive a maximum 8.0 seconds for one cycle (without printing board) and high speed printing is possible.
  • Squeegee movement and fitted off-contact can be controlled.
  • No coat printing equipment is standardized and both standardized printing and no coat printing can be changed by switch operation.
  • One-touch operation can be used in squeegee bias. Fine printing can be performed even if the board is difficult to thrust the ink.
  • The speed of the squeegee and scraper is digital display that is easy to confirm.
  • To enhance the safety, safety bar which is 3 direction self-standing type is employed so that the printer can be quickly stopped in case of an emergency.
