Soldering course

Lesson 1 • Workstation Organization and Layout

Teaches ergonomic and logical arrangement of tools and materials. A well-organized station improves efficiency and prevents accidents throughout training.

Lesson 2 • Fire Safety and Emergency Procedures

Covers fire extinguisher types, burn first aid, and emergency shutdown steps. Prepares students to respond correctly to common soldering emergencies.

Lesson 3 • Hazards and Health Risks

Covers chemical, thermal, and electrical hazards present during soldering. Builds the risk-awareness foundation required for all subsequent hands-on work.

Lesson 1 • Iron Tip Care and Maintenance

Covers tinning, cleaning, and storage procedures for soldering iron tips. Proper tip maintenance preserves heat transfer efficiency and extends tip lifespan.

Lesson 2 • Soldering Iron Types and Selection

Compares pencil irons, stations, and temperature-controlled units. Correct iron selection directly affects joint quality in all practical exercises.

Lesson 3 • Solder Alloys and Wire Formats

Explains tin-lead, lead-free, and specialty alloys along with wire gauges. Material choice determines joint strength, appearance, and compliance with safety standards.

Lesson 4 • Flux Types and Applications

Distinguishes rosin, no-clean, water-soluble, and synthetic fluxes. Proper flux selection prevents oxidation and ensures reliable joints across all project types.

Lesson 1 • Solder Wetting and Adhesion

Describes wetting angles, surface tension, and intermetallic bond formation. Wetting behavior determines joint integrity and is referenced in every technique chapter.

Lesson 2 • Role of Flux in Joint Formation

Explains how flux removes oxides and promotes wetting during heating. Flux chemistry directly affects joint quality and cleanup requirements in all projects.

Lesson 3 • Heat Transfer Principles

Explains conduction, thermal mass, and heat sink effects on soldering. Understanding heat flow prevents cold joints and component damage in all exercises.

Lesson 1 • Iron Application and Solder Feed

Teaches the correct sequence of iron placement, heat dwell, and solder introduction. This technique sequence is the core skill applied in all through-hole work.

Lesson 2 • Component Preparation and Insertion

Covers lead forming, polarity identification, and correct insertion depth. Proper preparation prevents rework and ensures consistent joint geometry.

Lesson 3 • Soldering Connectors and Large Components

Addresses heat management for high-thermal-mass connectors and multi-pin headers. These skills extend through-hole competency to real-world assembly challenges.

Lesson 4 • Inspecting Through-Hole Joints

Identifies acceptable and defective joint characteristics using visual criteria. Inspection skills enable self-correction and quality assurance in all subsequent projects.

Lesson 1 • Soldering SMD ICs and Fine-Pitch Devices

Applies drag soldering and flux-heavy techniques to SOIC and QFP packages. Fine-pitch skills are the highest-difficulty milestone in hand-soldering SMD work.

Lesson 2 • Soldering Passive SMD Components

Covers 0402 through 1206 resistors and capacitors using iron and solder wire. Mastery of passives builds the hand control needed for IC soldering.

Lesson 3 • Hot-Air Rework for SMD Components

Introduces hot-air station use for component removal and replacement. Hot-air rework completes the SMD skill set and enables professional-level repair work.

Lesson 4 • Tack Soldering and Component Placement

Teaches tacking one pad to hold components before full soldering. Accurate placement at this stage determines final joint quality for all SMD work.

Lesson 1 • BGA and Advanced Package Rework

Introduces reball and reflow techniques for ball-grid-array packages. BGA rework represents the highest complexity level in professional rework operations.

Lesson 2 • Pad and Land Restoration

Teaches cleaning, re-tinning, and repairing lifted or damaged pads. Pad restoration is critical before any replacement component can be installed.

Lesson 3 • Desoldering Through-Hole Components

Covers solder sucker and wick techniques for through-hole lead removal. Clean hole clearance is prerequisite to successful component replacement.

Lesson 1 • Automated Optical Inspection Basics

Explains how AOI systems detect defects and how to interpret their output. AOI literacy prepares students for production environments where manual inspection is supplemented.

Lesson 2 • Documentation and Traceability

Covers inspection records, nonconformance reports, and traceability requirements. Proper documentation supports corrective action and regulatory compliance in production.

Lesson 3 • Industry Quality Standards Overview

Introduces internationally recognised acceptability criteria for electronic assemblies. Understanding these standards frames all inspection decisions made in this chapter.

Lesson 4 • Defect Classification and Grading

Categorises defects as process indicators, nonconforming, or rejectable conditions. Accurate classification determines whether rework, repair, or scrap is required.

Lesson 1 • Soldering to Flexible Circuits

Addresses heat sensitivity, adhesive backing, and pad fragility of flex PCBs. Flex circuit soldering requires adapted technique to prevent delamination and damage.

Lesson 2 • Mixed-Technology Assembly Soldering

Combines through-hole and SMD techniques on a single board in correct sequence. Sequencing decisions directly affect joint quality and component survival.

Lesson 3 • Capstone Project Planning and Execution

Students plan and build a complete multi-technology assembly from schematic to inspection. The capstone integrates all course skills into a single evaluated deliverable.

Lesson 4 • High-Reliability Soldering Practices

Applies aerospace and medical-grade workmanship requirements to joint production. High-reliability standards represent the professional ceiling of hand-soldering competency.
