General Description
The intent is to provide the learner with a sound understanding of the fundamentals of soldering technology for SMT components. Upon completion you will have knowledge about SMT components, boards, solder, flux, soldering tips, temperatures, and techniques for soldering and de-soldering.

SMT & Fine Lead Repair Rework starts with understanding the terminology used, the materials, solder tip shapes, temperatures, and finally demonstrating soldering techniques in detail.

Target Audience

The target audience is those who require a sound understanding of the fundamentals of soldering to perform repair, rework, or touch-up on SMT assemblies using a soldering iron. The emphasis is on preserving the board, minimising damage, and perfecting tasks efficiently. This is an excellent course for:

• Product line management
• Production personnel
• Technicians
• Process engineering
• Quality
• Repair personnel
• R & D
• Sales & Marketing

This course is intended for those in technology-based roles, and who need a strong background in soldering technology. Therefore, the entry level of education and experience can be expected to vary greatly. Given the general nature of the course and the diverse background of the audience, this course will use terminology appropriate for a non-technical audience.

Course Prerequisites

There is no prerequisite for this course.

Book/Online Course Outline - SMT & Fine Lead Repair Rework

There are eight chapters.

Terminology
There are many new terms used in SMT soldering presented in this entry section. Terms include those pertaining to boards, vias, traces, solder joints, solder fillets, lands, pads, and many more. All are shown with detailed images.

Basics of SMT Soldering
An understanding of soldering is essential to working on today's complex SMT assemblies. Topics presented include:

• Soldering Systems
• Metals
• Soldering Action
• Temperature Effect
• Thermal Shock
• Soldering and De-soldering Steps

Solder, Flux and Cleaning
The impact of the type of materials used is presented and includes:

• Relationship of Solder, Flux and Thermal Energy
• Material Characteristics
• Soldering Temperatures
• Wire Solder /Types
• Flux and Types
• Paste Flux
• Intermixing Fluxes
• Cleaning Methods
• Solderwick Sizes and Use

Tip Care and Safety
Tip care and use is critical to keeping tools at their peak performance. Covered are:

• Tip Construction
• Tip Designs
• Oxidation
• Cleaning
• Sponges
• Tinning
• Tip Surface Problems
• ESD and Prevention

Tip Uses, Shapes and Temperatures
When soldering, knowing which is the proper tip, temperature and how to use it are key to successful soldering. Topics include:

• Identifying Tip Temperatures
• Key Factors in Tip Selection
• Solder Melt Temperatures
• Using to High or to Low Tip Temperature
• Uses for Different Tip Shapes
• Temperatures for Soldering and De-soldering
• Cleanup

Component Soldering
There are many leads styles used in SMT and this section teaches you how to solder each. Topics include:

• Recognising Damaged Leads and Repairing Them
• Polarity or Pin 1 Locations
• Tack Soldering for each Component Type
• Soldering Steps and Techniques for Each Lead Style

Component De-soldering
Sometimes it is more challenging to remove components than to solder them. It is easy to damage components or boards unless it is done properly. Topics covered for this area are:

• Component Attachment Methods
• Tip Preparation Requirements
• Tip Shapes
• Techniques

Removal Times for a Wide Range of SMT Packages

Inspection and Defects
Everyone who solders must inspect. Topics covered:

• Workmanship Standard Manuals
• Factors Affecting Performance
• Inspection with Magnification
• Over-Inspecting
• Prototypes and Production Inspection
• Solder Defect
• Categorising
• Setting up for Corrective Actions
