Specialist Tools and Equipment for Textiles and Electronic Systems

This lesson covers the specialist tools and equipment used when working with textiles and electronic systems, as required by AQA GCSE Design and Technology (8552), Section 3.2.8. Both material areas have unique tools and processes that you need to understand for the exam.

Tools for Working with Textiles

Measuring and Marking Out

Tool	Use
Tape measure	Measuring body dimensions and fabric lengths (flexible, 150 cm)
Pattern paper	Creating full-size pattern pieces from a design
Tailor's chalk	Marking cutting lines and seam allowances on fabric (brushes off easily)
Fabric scissors	Cutting fabric accurately (dedicated to fabric to maintain sharpness)
Pinking shears	Cutting fabric with a zigzag edge to reduce fraying
Seam ripper	Removing stitches without damaging the fabric
Pins and pin cushion	Temporarily holding pattern pieces to fabric, or fabric layers together

Cutting Tools

Tool	Use	Scale
Dressmaking scissors	General fabric cutting by hand	One-off and small batch
Rotary cutter	Cutting straight lines through multiple fabric layers	Small to medium batch
Die cutter / clicker press	Cutting identical shapes from fabric using a metal die	Large batch and mass production
Laser cutter	Precision cutting of synthetic fabrics (seals edges)	Batch and mass production
CAM cutting table	Computer-controlled multi-layer cutting using a blade or laser	Mass production (e.g. Gerber cutter)

AQA Exam Tip: Questions often link tools to scales of production. A laser cutter or CAM cutting table is appropriate for mass production, while dressmaking scissors and pins are used for one-off production. Be ready to justify your choice.

Sewing and Construction Tools

Tool/Equipment	Use
Sewing machine	Joining fabric with a lockstitch — faster and stronger than hand sewing
Overlocker (serger)	Trimming and enclosing raw edges with an overlocking stitch to prevent fraying
Embroidery machine (CAM)	Stitching decorative patterns automatically from a digital design
Iron and ironing board	Pressing seams open, applying interfacing, preparing fabric
Fusible web (Bondaweb)	Bonding fabric layers together using heat (iron-on appliqué)

Textile Finishing Equipment

• Heat press — applies heat-transfer vinyl or sublimation prints to fabric at a controlled temperature and pressure. Used for custom t-shirts, sportswear and promotional products.
• Screen printing equipment — screen, squeegee, emulsion, ink — used for printing designs on fabric.

Tools for Working with Electronic Systems

Measuring and Testing Tools

Tool	Use
Multimeter	Measuring voltage, current and resistance in a circuit
Oscilloscope	Displaying waveforms to analyse signal frequency and amplitude
Logic probe	Testing whether a point in a digital circuit is HIGH (1) or LOW (0)
LDR, thermistor, potentiometer	Input components used for sensing light, temperature and position

Construction Tools for Circuits

Tool	Use
Soldering iron	Joining electronic components to a PCB with solder
Solder (lead-free)	Forming a conductive joint between component leads and copper tracks
Desoldering pump (solder sucker)	Removing solder to correct mistakes or replace components
Side cutters	Trimming component leads after soldering
Wire strippers	Removing insulation from wire ends before connecting
Breadboard	Prototyping circuits without soldering (temporary connections)
Stripboard (Veroboard)	Building permanent circuits using copper strips and solder

AQA Exam Tip: When describing how to solder a component to a PCB, use this sequence: (1) heat the pad and component lead with the soldering iron tip, (2) apply solder to the joint (not to the iron), (3) remove the solder and then the iron, (4) allow the joint to cool without moving it. This is the correct technique examiners expect.

PCB Manufacturing

Stage	Tool/Process
Design	Circuit wizard or other CAD software to design the PCB layout
Transfer	Toner transfer (laser printer + iron) or UV exposure with photo-resist board
Etching	Ferric chloride solution dissolves unwanted copper, leaving circuit tracks
Drilling	PCB drill or pillar drill with 1 mm drill bit
Populating	Soldering components into drilled holes
Testing	Multimeter and visual inspection of solder joints

Programmable Components

Modern electronic products often include microcontrollers such as the Arduino or BBC micro:bit. These are programmed using a computer and can control outputs (LEDs, motors, buzzers) based on input signals (buttons, sensors).

Component	Description
Arduino Uno	Open-source microcontroller, programmed in C++ via the Arduino IDE
BBC micro:bit	Educational microcontroller with built-in LED matrix, buttons, accelerometer
PIC microcontroller	Compact programmable IC, widely used in commercial products
Raspberry Pi Pico	Low-cost microcontroller supporting Python and C/C++

Comparing Textiles and Electronics Tools

Factor	Textiles	Electronics
Primary joining method	Sewing (lockstitch, overlocking)	Soldering
Main marking tool	Tailor's chalk, pins	Component placement on PCB layout (CAD)
CAM tools	Embroidery machine, CAM cutter	CNC PCB drill, pick-and-place machine
Key safety risks	Needle injuries, burns from iron/heat press	Burns from soldering iron, fumes, electric shock

---

Health and Safety

Risk	Control Measure
Burns from soldering iron or heat press	Use a soldering iron stand, heat-resistant mat, allow cooling
Solder fumes	Use fume extraction or work near a fan
Needle injuries (sewing machine)	Keep fingers away from the needle, use a finger guard
Chemical exposure (PCB etching)	Wear gloves and goggles, use in well-ventilated area
Electrical shock	Never work on live circuits, use low-voltage supplies

Summary

Textiles and electronic systems each have a distinctive set of specialist tools. For textiles, the focus is on accurate cutting, sewing and finishing. For electronics, the focus is on prototyping, soldering and testing. In both areas, CAD/CAM technologies are increasingly used to improve accuracy and enable batch and mass production.
