HOTBEAM family

Low profile bottom heater for pre-warming of PCBs

Applications for underheaters range from pre-heating of PCBs for hand soldering tasks over pre-heating for automated machine rework to curing or cracking of underfill.

MARTIN offers a wide choice of underheaters. They can be classified by size of the heater and heater performance.
For preheating of PCBs (even double sided) IR heater are available up to a power rating of 2.000W. For efficient  rework on heavy electrical systems with flat bottom surface and LED PCBs the powerful under heater HOTPLATE-04 with 700W is recommended.

Option and Accessories

PCB Support for EXPERT and HOTBEAM 05

The secure and still flexible PCB fixation in EXPERT rework systems and HOTBEAM underheaters is realized with clamps and holders from 40,5 PCB Support family. Three different Flex-Support bars provide additional PCB support from underneath. This becomes important when using large scale PCB.

PCB Support HOTBEAM 04 (high profile)

When HOTBEAM 04 underheaters are used on the work bench, the magnetic clamps and holders from 55,5 mm PCB Support family are best to fix electronic assemblies above the heater. Also with these products best flexibility and long term reliability are in first place.

PCB Support HOTBEAM (table flush mounts)

With only 20mm working height over table top this PCB Support family is worlds flattest standard selection. Preferably these products are used in combination with table flush mounts. Even densely and until edge populated PCBs are hold properly and stable above the heater.

Flush Mount Set

Installing this set into the workbench underheater from HOBEAM Family become one with the table. The working height is reduced and this improves ergonomic quality of the workspace. Also electrical cables are stored away properly and do not provide danger or disturb in work flow.

Typ-K Temperature Meter

The in rework usually applied temperature sensors (thermocouple type K) are perfectly to use with HTM-06. The handheld temperature meter is battery driven and extremely reliable. The device can be calibrated on demand.


The set-up administration and back-up of underheater profile data is supported by the PC software EASYBEAM in best way. The underheater is connected via USB with the computer. Thus the operator has access to all device data and may even operate it remotely, too.
