Multi Level-Dryer

Model: HET120

het1201

Multi- level dryer for 120 pcbs, horizontal throughfeed.  

Technical data

  • Function: drying pcbs after coating
  • Number of heating circuits: 120 pcbs (1 pcb per rack)
  • Loading capacity: 120 pcbs per hour
  • Min. time of 1 cycle: 30 secs.
  • Temperature approx.: 90-100 °C
  • Connection load: 80 kW
  • Exhaust air: Max. 3,000 m³/h
  • Dimensions of Pcb's: min. 250 x 350mm - max. 610 x 610mm
  • Thickness: min. 0.4mm - max. 5.0 mm
  • Dryer Dimensions: (L) 3m x (H) 3.8m x (W) 2m
  • In- and outfeed: 1500mm
  • Total length: 4.5m
  • Panelling: Steel sheet, powder-coated
  • Frame: RAL 7035 (light- grey), tubular steel, IC 198 blue painted

Function

Freshly coated pcbs are dried in a quick and homogeneous way. One pcb lies on one rack. The rack raises upwards in 30 sec. cycles, is pushed to the outfeed side and then lowers downwards again.

  • Infeed: The pcbs enter the dryer on transport belts. The rack raises above the transport (belt) level and takes one pcb. The transport belts are folded down. They return as soon as the next pcb will enter.
  • Outfeed: The rack drives below the transport (belt) level. The dried pcb is left on the belts and can leave the dryer. The outfeed belts are folded down so far, to allow the emptied rack to be pushed back to the infeed.They return as soon as the next pcbs have to be fed out.

The pcb’s pass one evaporation zone, three heating circuits and one cooling zone. The temperature of each heating circuit can be controlled separately. The typical drying temperature of 90-100°C has been achieved after the first heating circuit. It is hold in the second and third circuit. Before leaving the dryer, pcb’s are cooled down to approx. 30°C.

Temperature profile

The profile depends fundamentally on the ink. The following values, based on experiences, are typical:

  • Evaporation: 15 min.
  • Heat up: 5 min.
  • Hold on: 25 min.
  • Cool down: 15 min.
  • Total time: 60 min.  

Advantages

  • No subject to the pcb-size
  • Reproducible temperature distribution on the panel
  • Careful transport
  • Control of temperature for each heating circuit
  • No buckling or distortions of pcbs
  • Connection of lines possible
  • Visualization of process
  • Room saving because of compact design

Options / Alternatives

  • Vertical dryer VDH 144-352
  • IR-Dryer
  • Grip-dryer for very thin pcb’s
