MYDATA MY12 Hydra II automatic machine of the efficiency of 21000 elements per hour

  • maximum plate size: 400 x 470 mm
  • accuracy: 0,015 mm
  • angle of rotation: arbitrary (resolution 0,01 degree)
  • assignment: elements from 0402 to QFP, BGA, CSP of sizes up to 56 x 56 mm
  • feeding system:
    • tape feeders: 8, 12, 16, 24, 32, 44, 56 mm (maximum 144 tracks)
    • vibration feeders: from SO-8 to PLCC-84
    • tray feeders: QFP(pitch 0,25 mm – 1 mm), BGA (pitch 0,3 mm – 1,27 mm)
  • electric test: resistors, capacitors, transistors, diodes (including Zener)

It is equipped with two assembly heads:
1/ “HYDRA SpeedMount” – assigned for most of elements packed in 8 mm and 16 mm tapes, and for integrated circuits in SO8, SO14, SO16 casings. It reaches the high working speed (maximum 21000 circuits/ hour) with ensuring the high assembly precision thanks to apply the mechanism with 8 suction nozzles and the optical alignment.
2/ “MIDAS” head – assigned to assembly all other subassemblies; it is equipped with two optical mechanisms of precise alignment of elements (Dual Vision System and Linescan Vision System) reaching the unusual assembly precision with keeping the high speed (maximum 6100 circuits/ hour); a system of electric verification of resistors, capacitors and diodes is also applied, which makes impossible assembling the component not compatible with the project.


MYDATA TP9UFP Hydra Speed Mount automatic machine of the efficiency of 14400 elements per hour

  • maximum plate size: 200 x 470 mm
  • accuracy: 0,07 mm
  • angle of rotation: arbitrary (resolution 0,03 degree)
  • assignment: elements from 0603 to QFP208
  • feeding system:
    • tape feeders: 8, 12, 16, 24, 32, 44, 56 mm (maximum 96 tracks)
    • vibration feeders: from SO-8 to PLCC-84
    • tray feeders: to QFP-208
  • electric test: resistors, capacitors, transistors, diodes (including Zener)

Mydata TP9-UFP is equipped with two assembly heads:
1/ “HYDRA SpeedMount” – assigned for most of elements packed in 8 mm tapes. It reaches the high working speed (maximum 14400 circuits/ hour) with ensuring the high assembly precision thanks to apply the mechanism with 8 suction nozzles and the optical alignment.
2/ “Z-mount” head – assigned mainly to assembly integrated circuits and subassemblies in cylindrical casings, connectors, inductance etc. A mechanism of precise mechanical alignment of elements as well as a two-point system of electric verification of resistors, capacitors and diodes is also applied here, which make impossible assembling the component not compatible with the project.


DEK 248 silk-screen printer

We purchased the DEK 248 silk-screen printer of the accuracy of 0,025 mm and the working area of 432 x 405 mm in order to precise spread of the soldering paste. The correct positioning of the printed plate in relation to the stencil is ensured by two camera tracks cooperating with the system of picture recognizing, making impossible the overprint in case of any fault. This silk-screen printer enables spreading the soldering paste even under elements of the half-tone screen of 0,3 mm. We apply only metal stencils to spread the paste and the adhesive.
