Reflow Methods

Convection Oven
Convection Oven Area Heated
Whole product.

Key Features
  • Non-contact heating
  • Tight peak temperature control
  • Uniform heating across product
  • High throughput
Diode Laser
Diode Laser Area Heated
Area of laser focus and surrounding area through conduction.

Key Features
  • Non-contact heating
  • Area of focus can be as small as 0.6mm
  • Precise energy output control
  • Energy absorption is material-dependent
Focused Hot Air
Focused Hot Air Area Heated
Area defined by nozzle design, air dispersion, and conduction.

Key Features
  • Non-contact heating
  • More local than a convection oven
  • Tight temperature control
Hot Bar / Thermode
Hot Bar / Thermode Area Heated
Area of contact and surrounding area through conduction.

Key Features
  • Contact heating
  • Heat transfer dependent on surface area of contact
  • Thermodes wear with use
Hot Plate
Hot Plate Area Heated
Entire product through conduction from contact surface out to extremities.

Key Features
  • Contact heating
  • Heating rate dependent on contact surface area
  • Heats from the “bottom” up
Induction
Induction Area Heated
All conductive materials within inductive field and surrounding area through conduction. Field strength decreases with the square of the distance.

Key Features
  • Non-contact heating
  • Available in very high energy capacity
  • Heats materials with higher electrical resistance faster (e.g. steel faster than copper)
  • Field shape is a function of coil shape
Infra Red (IR)
Infrared Area Heated
Area of IR exposure and surrounding area through conduction.

Key Features
  • Non-contact heating
  • Energy absorption is material dependent with metals being poor absorbers
  • Area of IR exposure can vary from as small as an 8mm spot to a theoretically unlimited area
Resistance
Resistance Area Heated
Conductive material between electrodes.

Key Features
  • Contact heating
  • Performance partly dependent on contact area between part and electrodes
Soldering Iron
Soldering Iron Area Heated
Point touched and surrounding area through conduction.

Key Features
  • Contact heating
  • Heat transfer dependent on surface area of contact
  • Tips wear with use
Torch
Torch Area Heated
Area of flame focus and surrounding area through conduction.

Key Features
  • No physical contact; flame touches part
  • Available in very high energy capacity; with increased capacity comes increased flame size
  • Open flame ignites flammable materials
