7 Tutorial – Soldering or unsoldering a component
In what follows, the soldering and unsoldering process will be described step by
step.
7.1 Insert the PCB
NOTE
ESD sensitive components!
Electronic components may be damaged by electrostatic discharges. Please observe
the warnings on the packaging or contact the manufacturer or supplier. To protect
these components, the system should be placed in an electrostatic protected area
(ESD = electrostatic discharge).
The HR 550 can be easily integrated in environments of this kind. Using one of the
front buttons, the user can connect for example an ESD wristband. The housing of the
HR 550 is connect via power cord to the earth wire of the supply network.
When handling the device, observe all general safety measures normally required for
ESD sensitive components.
CAUTION
Material damage caused by overtightening the PCB holder!
Tighten all screws just enough to ensure that the PCB is securely fixed. Excessively
high tightening torques can cause damage to threads and circuit boards!

Insert a PCB:
a) Hold down the unlock key on the front of the bottom heating, while pulling the
bottom heating forward until the PCB frame is easily accessed.
b) Loosen the two knurled screws (1) and adjust the distance of both rails approx-
imately to the width of the circuit board.
c) Loosen the four knurled screws (3) and adjust the distance of the PCB holder to
the dimensions of the PCB. Take also any interfering components into account.
d) Tighten the four knurled screws (3).
e) After loosening the knurled screws (4), the clamping can be adjusted to the po-
sition and the angle of unsymmetrical PCBs as well.
