The innovative quick connector - simple, safe and
economical:
PCB terminals with spring connection and direct PUSH IN
technology. A milestone in connection technology.
Amazingly simple and simply amazing in practice:
• Connect and easily detach solid wires or wires with
wire-end ferrules without using tools
• Processed automatically in the reflow or vapour phase
• Potentials and clamping points marked clearly by
coloured push buttons

World-class design-in and processing phases, and
suitable for a vast range of applications.
PCB terminal for fully automatic assembly using
reflow soldering (SMD), with PUSH IN wire
connections. Conductor insertion and slider
operation from the same direction (TOP).
• Solid & flexible conductors with wire-end
ferrules need only to be inserted and they are
ready.
• When connecting stranded wires without wireend ferrules the actuating element is used to
open the terminal point
• Intuitive handling – since the wire-entry area and
handling area are clearly separated.
• Packaged in tape-on-reel
• Conductor outlet direction 180°

Reflow soldering profile
The perfect soldering profile for SMT Surface Mount Technology is one the most exiting question in SMT production.
But there are more than one correct answer: The diagram of temperature-on-time is related to processing features of
solder paste and to maximum load of components.
We have to consider the following parameters:
• Time for pre heating
• Maximum temperature
• Time above melting point
• Time for cooling
• Maximum heating rate
• Maximum cooling rate
We recommend a typical solder profile with associated process limits. With preheating components and board are
prepared smoothly for the solder phase. Heating rate is typically ≤ +3K/s. In parallel the solder paste is ‚activated’. The
time above melting point of 217°C the paste gets liquid and components and boards begin to connect. The maximum
temperature of 245°C to 254°C should stay between 10 and 40 seconds. In the cooling phase at ≥ -6K/s solder is
cured. Board and components cool down while avoiding cold cracks.
