E2 : SMT Soldering and Debugging
This page may be out of date due to recent changes during the ongoing pandemic. Please contact us at tiw@utexas.edu or visit us in the EERC during our current hours.
About
Electronics Lab 2 (E2) is predominantly used for soldering and desoldering surface mount devices. Surface mounted technology is a method in which the electrical components are mounted directly onto the surface of a printed circuit board (PCB). An electrical component mounted in this manner is referred to as a surface-mount device (SMD). If you need to do some basic soldering with thru-hole components or wires, please see the E1 page for equipment related to thru-hole soldering.
You must get E2 training to use any of the machines in this lab. You must be E1 trained before you are E2 trained.
Please sign up for E2 training on SafetySpot with your UT EID here.
Aoyue Int866 Rework Station TRAINING REQUIRED
About
This rework station consists of three components:
- Soldering Iron
- Hot Air Gun
- Preheater
This station is useful for desoldering and resoldering, fixing cold joints, and salvaging components with a large number of pins.
Access
Anybody with E2 Training can use this device. There are 4 stations available for use. This rework station consists of three components:
Cost
This machine is free to use. Solder, solder wick, and tweezers are available for checkout in the E2 toolbox at the Garage.
Resources
Warnings
- This station has an auto-sleep feature. See manual to activate and deactivate.
- Always tin the tip to prevent oxidation and reduced heat conductivity. Video
- Hot air may damage components or plastic parts (e.g. headers). Keep the hot air gun moving to prevent excessive heating.
- When using the hot air gun, start at a low air flow to prevent flying components.
- If you see black goo appear with a horrendous smell, STOP. This is likely the glue that connects the copper to FR4 laminate. Do not heat one area for too long.
Microscope TRAINING REQUIRED
About
Use these microscopes to check the quality of your soldering work. If you encounter a blank screen, press the top right button on the black panel. Adjust focus with the gold knob. Lights are controlled by a switch on the power cord.
Access
Anybody with E1 Training can use this device.
Cost
This machine is free to use.

Mantis Elite Stereo Microscope TRAINING REQUIRED
About
The Mantis has 2X-20X magnification, and is useful for viewing PCBs at varying angles.
Access
Anybody with E2 Training can use this device.
Cost
This machine is free to use.
Resources
Oscilloscopes
Access
While a multimeter may provide data on voltage or current at a specific point in time, an oscilloscope displays a graph of an electrical signal over time. E2 provides several digital phosphor oscilloscopes (DPOs) for use. You will need access to E2 to use them.
Cost
This machine is free to use. Cables are provided on racks.
Resources
Warnings
- Your circuit should be entirely complete before connecting the oscilloscope.
- NEVER connect the ground clip to anything other than ground. This will blow up the oscilloscope, as it is a dead short.

Function Generators TRAINING REQUIRED
About
Function generators can produce signals at a variety of frequencies and amplitudes. They can generate sine, square, triangular, and sawtooth waves. Function generators are commonly used to test circuit responses to known input signals. For example, you can feed a signal into an amplifier circuit to test its efficacy. They can also be used to design audio and various filter circuits.

Multimeters TRAINING REQUIRED
About
These multimeters offer the same functionality as small handheld multimeters provided for checkout in the Garage. However, they feature higher accuracy and measurement speed. In addition, these can be interfaced with USB and other instruments for automated testing or data collection.
Access
Anybody with E1 Training can use this device.

Resources
Warnings
- Before turning on the power supply, do not connect any load
- Before shutting down, disconnect the load
- If running an inductive load (magnetic coils, DC motors, stepper motors, etc.), change the voltage or current slowly, and NEVER turn the power supply on or off with an inductive load connected.

Spectrum Analyzer TRAINING REQUIRED
About
Spectrum Analyzers measure the amplitude of an input signal versus frequency. Unlike an oscilloscope, which measures in the time domain, spectrum analyzers display frequency on the x-axis. This specific spectrum analyzer can compare 4 traces at once.
Access
Anybody with E2 Training can use this device.
Cost
This machine is free to use.
Resources
Warnings
- Ensure proper grounding.
- Protect the RF input connector - avoid cable bends.
- Avoid overpowering the analyzer. The RF input should not exceed +30 dBm. DC voltage cannot exceed 50 V.
- If a probe is used, do not connect the ground lead to high voltage.
