General Description
The intent is to provide the learner with a sound understanding of the standards for inspecting assembled SMT & through-hole components. Upon completion you will have knowledge about inspection standards for alignment, solder connections, and boards. You will also learn about process control and audits, ESD, and much more.

SMT & Through-Hole Workmanship Standards starts with understanding the terminology. It presents information about each of the most common types of terminals and how leads are to be attached, followed by information about the forming and insertion for leads into a board, then after solder what are acceptable solder connections. If jumpers are required the information presents how they are to be routed and solder attached.

Target Audience
The target audience is those who require a sound understanding of the standards for insertion and solder connections. This pertains to all personnel who handle or come in contact with electronic assemblies.

• Product 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 electronic assembly requirements. 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 & Through-Hole Workmanship Standards

There are eight chapters.

Standards and ESD (Electro-Static-Discharge)
Key areas presented set up an understanding about reading documents, which documents are essential, and why ESD must be kept in check.

• Explanation of workmanship standards and associated documents
• Terminology
• ESD awareness issues

Connectors, Terminals & Wires
Assemblies may require the use of assorted terminal types, including:

• Turret terminals
• Bifurcated terminals
• Hook terminals
• Pierced terminals
• Perforated terminals
• connecting wires to each of the above

PTH Mounting and Assembly
The preparation of leads, the proper insertion into the boards, and how to mount assorted through-hole parts are presented.

• Forming, insertion and mounting of through-hole components such as axial, radial DIP and connectors
• Mechanical assembly for power transistors
• Stress relief
• Insulators
• Lead clinching
• Mounting

SMT, PTH Soldering & Handling
Soldered connection for both SMT and through-hole must comply with certain requirements to be acceptable.

• Different methods of soldering
• Board handling
• Exposed lead metal
• Flux interaction
• Surface mount and leaded component soldering
• Solder connection acceptance and rejection criteria
• Cleanliness
• Inspecting and testing for residues

SMT Component Workmanship
This module covers the issues involved in soldering and inspecting SMT components, including:

• Adhesives
• Lead styles
• Alignment
• Mounting height
• Solder fillets
• Lead styles (gull wing, J lead, round, flattened) · Various components ( clips, MELFs, bottom only terminations, castellations and butt joints

Discrete Wires and Jumpers
Discrete wiring refers to wires wrapped on a post (non-solder), or added as jumper wires and then soldered.

• Turns
• Wrap counting
• Material damage
• Jumper wires
• Staking jumpers
• Attaching jumpers to SMT and PTH leads
• Insulation
• Wire routing
• Clips and clip attachment
• Routing jumpers

Conformal Coating and Solder Mask
Coatings are used to protect surfaces from a variety of factors such as moisture and abrasion.

• Coating requirements
• Thickness
• Adherence
• Curing
• Inspection
• Solder mask requirements

Process Control and Health
Process control is vital to success in manufacturing.

• Process verification
• Data collection
• Using SPC
• Using procedures
• Audits
• Inspection
• Documenting defects
• Basic health and safety
