Circuit boards are tested before the components are mounted. In addition to the usual spring-loaded contact pins movable only in the axial direction and applied to the circuit board, other contact pins movable in other directions are used and combined in pairs or groups mounted on supporting ...
A test circuit, system, and method are provided herein for testing one or more circuit components arranged upon a monolithic substrate. According to one embodiment, the system may include a test circuit and one or more circuit components, all of which are arranged upon the same monolithic substr...
The invention relates to a device for testing electronic components comprising a stimulating device which galvanically contacts the component. Said stimulating device excites the component by means of electric application to generate a field in the surrounding space. In addition, a measuring device is ...

Another similar yet different opportunity, StoryBook, allows exposing UI components as a graphic catalog where one can walk through the various states of each component (e.g. render a grid w/o filters, render that grid with multiple rows or with none, etc), see how it looks like, and ...
Advantages: can test JTAG-compatible components together The boundary-scan method, also known as JTAG (IEEE Std 1149.1), is a debugging method for integrated circuit (IC) chips. PCBs that support boundary scans have a JTAG interface port that allows access to ICs and embedded logic. JTAG test...
The device draws from similar equipment used when making large printed circuit boards, testing and measuring different components on a roll of printed ... S Harris - 《Engineer》 被引量: 0发表: 2012年 Re-configurable architecture for automated test equipment An adaptive test system includes one ...
First, the in-circuit test is performed as part of the circuit board’s manufacturing process and steps. It checks the board components using what’s commonly referred to as a bed of nails, where an array of spring-loaded pins makes contact with the board at specific points. In contrast,...
