Bus Bar Thickness: Helpful Advice for Soldering Design

Summary for bus bar thickness Discussion

Bus bar thickness and soldering relation is raised as an abstract design question: Satish Khsatriya asks what relationship exists between copper bus bar thickness and soldering on a PCB, and how to decide the thickness for a project. The only response does not give a technical sizing rule; instead, it advises that the question is too general to answer well because there are many “ifs, ands, & buts.” The reply says people are often discouraged from tackling broad questions and recommends posting the full specifics of the situation to get useful help. In other words, the thread does not settle the engineering issue, but it does make clear that bus bar thickness depends on the application details and that more context is needed before a meaningful recommendation can be made.
