What You Should Already Know:
There are no prerequisites for this course
This course is intended for operators who already understand the basics of hand soldering, and simply need to learn the differences between soldering with tin-lead vs. lead free solder.The course will demonstrate the subtle differences between tin-lead and lead-free soldering techniques & inspection criteria. This program is designed to assist operators and soldering technicians to make the transition to lead-free with knowledge and confidence.The course will describe the new types of solder alloys, and discuss the higher melting temperatures used in lead-free that can potentially damage the assembly.
Section 1 also explains required changes due to increased surface tension, more active fluxes, and additional cleaning considerations.
Section 2 demonstrates modified techniques for soldering through-hole components into plated-through holes, and wires to pierced terminals, then demonstrates PTH rework / vacuum extraction - focusing on damage prevention from increased soldering temperatures.
Section 3 compares tin-lead / lead-free solder joints to the visual acceptance criteria from IPC-A-610 with original microphotography of target conditions, textural differences, minimum and maximum solder, wetting requirements, cold / disturbed joints, fractures, lifted lands, thermal damage, bridging, projections, blowholes and solder balls.
- Demonstrate Proper Techniques for Through-Hole and Plated-Through-Hole
- Clearly Understand Soldering Differences Between Tin-Lead and Lead-Free
- Become More Familiar with IPC-A-610 Standard
- Demonstrate Usage of Various Tools for Lead-Free Soldering
Course Time: 23 Minutes
Testing & Certificate:
A Certificate of Completion will be issued to the student upon Completion of the testing requirement of the course. A passing grade of 70% is needed to receive the certificate. The student will be allowed to take the test a total of 3 times to achieve a passing grade.
