This training is based on the IPC document IPC-A-630 with the name box building. Box building is the compilation of an end product. The various modules, components that are already made in advance within the electronics assembly, are assembled into an end product.
A printed circuit board with components on it (the PCBA or printed circuit board assembly), a cable harness and various other items that must be assembled in the end product. This is all put together, using screws, nuts, clips, cable ties and all kinds of things that are necessary for this (such as buttons).
Ultimately, it is all about getting into the housing and thus becoming an end product that is delivered to a customer. We are talking about consumer products, such as GSMs, TVs and coffee machines. But we are also talking about industrial electronics.
Large machines that are used in industry to make things, such as aircraft electronics, but also coffee machines in aircrafts that are assembled and then screwed into those aircrafts. This training then educates employees and indicates what the requirements are for such connections and installations and what they should pay attention to when inspecting screw connections (clip connections).
In principle, all connections, all actions that are done when assembling an end product are covered in the IPC-A-630 box building specialist training.
