Station for repairing surface mount device electronics

About

The surface mount rework station is good for assembling surface mount circuits by hand and also for repairing surface mount circuits. Additionally, it can be used for traditional through-hole circuits.

Features:

• Both the soldering iron and the hot air gun have a temperature range of 100 – 480C.
• Digital PID technology to enhance temperature stability
• Adjustable airflow and temperature control
• Intelligence self-detection function features safe personal operation
• Auto and manual startup function of airflow temperature
• Sensor switch enables operating mode when picked up or standby mode when laid down
• Automatic cooling function for prolonging the heater’s life and protecting the hot air gun
• ESD design of soldering iron to protect sensitive components
• International standard heater for convenient use and exchange
• Plastic holder for placing the hot air gun
• Alloy iron stand for keeping the iron from flammable materials
• Good for soldering and desoldering SOIC, CHIP, QFP, PLCC, BGA,SMD,etc.

Safety

• Both the iron and the hot air get HOT – use with caution.
• Turn the unit off when not in use.

Safety

Important safety information and procedures:

• Set the output voltage BEFORE connecting to a circuit
• Do not short the output leads to each other
• Turn power off when done using power supplies

Getting Started

Materials

Electronic components, circuits, and assemblies

Power and Speeds

Each power supply has its power ratings listed on the case.

Tips and Tricks

Before connecting to a circuit set the output voltage to the desired value.

The General Radio 1386 is a random noise generator that can generate noise in three spectrums.

About

The General Radio 1382 is a Random Noise Generator that can generate noise in one of three spectrums

• “White” noise – constant energy per cycle bandwidth
• “Pink” noise – constant energy per octave bandwidth
• “USASI” noise for calibrating sound level meters as specified in the USASI Standard S1.4

This type of signal is useful for room-acoustics studies, loudspeaker and microphone test, psychoacoustic tests, filter tests, crosstalk measurements, calibration checks on recording systems, and modulation of signal generators and test oscillators.

Safety

Important safety information.

• Keep fingers clear when operating either machine!

Materials

Power and Speeds

Maximum open-circuit output voltage is at least 3V RMS for any bandwidth
