Dedika is a platform for learning by doing: whether it's creating a business proposal, becoming a manicurist, or using a new tool, for example. Whatever your goal, the best content on the subject already exists. But it's often in another language, expensive, scattered around, lacking practical activities, or part of a course that's too long for a busy routine. That's why Dedika has its own method: we find this material wherever it is, organise what makes sense for your goal, review it with the help of experts who are available to answer questions, and create practical exercises so you can learn by doing. You are the most important part of your journey and no one knows it better than you: choose the content and course length, decide whether to learn online or offline, and pick your preferred format. It could be video, text, audio, or a summary. Your way, only with what makes sense for you. Here, every moment of dedication counts for more and you reach what matters faster.

Our courses include a summary at the end of each chapter, from which you can download a PDF and print it.

Whether you're pursuing CIS certification or sharpening your inspection judgement, this course delivers the technical depth you need.

Dedika for businesses

What you will learn:

This course walks you through the complete IPC-A-620 standard, from foundational terminology and the three-class system to detailed acceptance criteria for crimping, soldering, connector assembly, and harness routing. You will learn to distinguish acceptable conditions from process indicators and defects across all product classes. The training also covers structured inspection methodology, nonconformance documentation, and the use of measurement tools. You will gain familiarity with related IPC standards, ESD control practices, and engineering drawing interpretation. By the end, you will be prepared to perform consistent, defensible harness inspections in a production environment.

Acceptability Classifications and Conditions

Lesson 1 • Applying Class Requirements to Inspection
Demonstrates how class designation changes acceptance thresholds for identical features. Builds skill in adjusting judgment based on the specified product class.
Lesson 2 • Common Classification Errors and Prevention
Identifies frequent misclassification mistakes and their quality consequences. Reinforces correct classification habits through error analysis and corrective strategies.
Lesson 3 • Acceptability Condition Categories
Defines Acceptable, Process Indicator, and Defect conditions and their inspection implications. Correct condition identification determines pass, monitor, or reject outcomes.
Lesson 4 • Product Classes Defined
Explains Class 1, Class 2, and Class 3 distinctions based on end-use reliability requirements. Class selection drives all subsequent acceptance criteria throughout the standard.

Chapter 3See details

Wire and Cable Preparation Requirements

Lesson 1 • Insulation Integrity Requirements
Defines acceptable insulation condition after cutting and stripping operations. Insulation integrity directly affects dielectric performance and assembly safety.
Lesson 2 • Coaxial and Shielded Cable Preparation
Addresses preparation requirements specific to coaxial, shielded, and multi-conductor cables. These cable types have unique preparation steps beyond standard wire stripping.
Lesson 3 • Preparation Inspection Techniques
Introduces visual and measurement methods for verifying wire preparation compliance. Consistent inspection technique ensures repeatable and objective quality judgments.
Lesson 4 • Wire Stripping Acceptability Criteria
Covers nick, scrape, and cut-strand limits for stripped wire ends across all classes. Correct evaluation of stripping quality prevents electrical and mechanical failures.
Lesson 5 • Conductor Condition After Stripping
Examines acceptable conductor appearance including oxidation, discolouration, and strand integrity. Links conductor condition to long-term electrical performance.

Chapter 4See details

Crimping and Mechanical Terminations

Lesson 1 • Mechanical Connector Terminations
Addresses screw, clamp, and IDC termination acceptance criteria beyond standard crimping. Mechanical terminations require distinct evaluation methods from crimp-based connections.
Lesson 2 • Crimp Termination Fundamentals
Explains the mechanics of crimping and how crimp quality affects electrical and mechanical performance. Foundational understanding supports accurate evaluation of crimp acceptability.
Lesson 3 • Open-Barrel and Closed-Barrel Terminals
Distinguishes acceptance criteria between open-barrel and closed-barrel terminal types. Each terminal geometry has unique inspection points and defect indicators.
Lesson 4 • Insulation Barrel Crimp Criteria
Covers acceptance conditions for insulation support crimps and strain relief features. Proper insulation barrel crimps prevent conductor fatigue and insulation damage.
Lesson 5 • Wire Barrel Crimp Acceptance Criteria
Details acceptance conditions for wire barrel crimps including conductor fill, bellmouth, and strand visibility. Correct wire barrel evaluation is critical to electrical connection integrity.

Chapter 5See details

Soldering Requirements for Wire Harnesses

Lesson 1 • Solder Joint Acceptability Fundamentals
Establishes the visual and dimensional criteria defining an acceptable solder joint. Understanding solder wetting, coverage, and fillet shape is prerequisite to all solder inspection.
Lesson 2 • Flux Residue and Cleanliness Criteria
Addresses flux residue acceptability and cleanliness requirements after soldering. Residue type and quantity affect long-term reliability and must meet class-specific criteria.
Lesson 3 • Soldering to Terminals and Lugs
Covers acceptance criteria for wire-to-terminal and wire-to-lug solder connections. Terminal solder joints have specific fill and coverage requirements by terminal type.
Lesson 4 • Solder Defect Identification
Identifies and classifies common solder defects including cold joints, voids, and bridging. Defect recognition skills enable accurate rejection and root-cause analysis.
