DEK International has developed the Automatic Paste Dispenser II (APD II). Building on the advantages of the original APD, DEK’s APD II can work in parallel alongside other printer functions to minimise time loss and deliver consistent paste volumes to the stencil for process control.
DEK’s APD II allows complete control of the dispensing profile by optimising speed, pressure, position and frequency to ensure paste deposition precisely when and where required. This functionality, in addition to volume consistency and a controlled dispensing stroke, is increasingly important as the electronics industry continues to move toward ultra-fine-pitch devices. The APD II helps to eliminate “lost areas” of material, which can contribute to yield losses, particularly with finer-pitched components.
Maintaining paste on the stencil without stopping the production process for manual replenishment can save more than an hour of production time per day and enables higher throughput rates. Other advantages of DEK’s APD II include cartridge changeover requiring less than two minutes, paste level detection, compatibility with industry-standard material syringes and fully programmable dispense stroke (length) and position (x, y). DEK’s APD II is available on most DEK print platforms.
