3.2.2 Handling & Solder recommendations
The TGP package can be wired and soldered by using
standard solder equipment.
The non-functional connection is being used for me-
chanical stability. It can also be used to integrate a tem-
perature sensor (e.g. PT100) close to the TGP to moni-
tor the package temperature.
Reflow procedure for mass production will be accord-
ing IPC/JEDEC.
IMPORTANT NOTE:

3.3
The TGP has to be mounted between a hot and cold
source so that:
 There is space for placing electronic components
 Maximum thermal performance can be achieved, by
 No pulling force acts on the three contact pads of
A practical example is described for an application with
a hot source adaptor (for instance connected to a pipe
with hot liquid) and a heat sink in ambient air.
Practical energy harvesting application
directly next to the TGP, in case of an embedded
application with a Printed Circuit Board (PCB)

actual prototypes have to be manually soldered:
270 ºC max. and 5 seconds max.,
to connect wires to the TGP contact pads.

TGP position
A good mechanical connection can be achieved by us-
ing a clamp or stainless steel bolts to mount the TGP
between the hot and cold sources.
Important to observe is:



Assembly of TGP
Avoid parallel leakage of thermal energy (bypassing
the TGP) by using stainless steel bolts, instead of
steel bolts. They have a reduced thermal
conductivity.
Thermal isolator material around the bolts improves
mechanical stability.
When using bolts to clamp the TGP between two
metal surfaces, the target force is 35 cNm. Bolts
should be fastened in an alternating manner in small
steps.
Thermal paste can be added between the TGP and
both the hot and cold sources.
Alternatively Graphite foil can be used to achieve
good long-term thermal performance (i.e. eGraph
type Hitherm 2505, 127µm.)
