Postsolder

Postsolder is an online, collaborative knowledge base focused on soldering and electronics assembly. Initiated in 2010 by a coalition of hobbyists, educators, and engineers, it aims to provide reliable, neutral information on techniques, materials, tools, and safety practices related to soldering. The project emphasizes verifiability, community participation, and accessible documentation for both beginners and professionals.

Its articles cover solder alloys (including leaded and lead-free options), flux chemistry and cleaning, PCB finishes, and joint formation. It also describes soldering techniques (hand soldering, hot-air rework, wave and reflow processes), inspection methods, repair and rework strategies, and environmental and safety considerations such as fume control, ventilation, and handling of hot surfaces. Tutorials strive to present step-by-step instructions with cautions and best-practice checks.

Content on Postsolder is generated and moderated by volunteers. Submissions undergo editorial review to maintain accuracy and neutrality, and all article revisions are tracked in a version history. The project follows licensing that allows reuse and adaptation under a permissive Creative Commons arrangement, and it maintains talk pages and citation guidelines to support reliable sourcing and discourse.

Since its inception, Postsolder has grown to host thousands of articles and regional community groups. It is used by hobbyists, educators, and small manufacturers as a reference source and teaching aid, contributing to standardized safety practices and broader access to soldering knowledge.
