Chapter 7 Living with ICT Problems 1 Chapter 7 Living with ICTs: Problems and how we Cope with them 7.1 Introduction Most people experience problems with machines and new ICTs are no exception. Living and working with and around machines of is not only a story of benefits, but also of problems, uncertainties, demands for change and conflicts.
ICT has introduced new (amended) General Terms and Conditions of Supply as well as General Terms and Conditions of Procurement. These new (amended) General Terms and Conditions, submitted to the Chamber of Commerce and replacing the General Terms and Conditions earlier used, are effective as of 1 July 2017 and apply to all ICT’s deliveries and procurements as well as all negotiations and (new) agreements with ICT. ICT’s new General Terms & Conditions can be read, downloaded, saved and printed through the links below. In case of questions, please turn to the Legal Department, +31889082000.

Currently, various ICT technologies and vertical domains are converged in the IoT to provide new levels of functionalities and services to users. For example, smart parking services will converge with in-vehicle communications, location-based tracking services and navigation and infotainment services within cars. With the ICT-supported educational system, the acquisition of knowledge and skill can be boosted by it, which then can empower the students for lifelong learning. When the ICT can be used properly, some of the ICT technologies, such as computer and internet, has.

During in-circuit tests (ICT) all components on the PCB are measured. In doing so, defective components are detected and can be replaced accordingly.
Function tests (FCT) check the entire intended function of a PCB. According to the intended area of use, the environment is replicated and the electrical performance of the PCB is checked.
In order to optimally fulfill the contacting requirements, various test probes are available. These differ in terms of installation height, grid size (possible distance between probes), tip style, and type of connection – see following illustration. The electrical connection is achieved either with a solder cup or wire-wrap, with or without cable (wireless).
Contacting loaded PCBs
- Standard PIN und PAD contacting
- Dual-stage contacting
- Limited space available
- Contacting of contaminated surfaces
- Contacting of beads on the PCB
- Connection without cable
- Small pads and grids
- Robust probes for harsh conditions
International standard spring-loaded test probes (GKS) (inch)
Available in two different versions: Standard working stroke (4.3 mm) and longer working stroke (9.3 mm) for dual-stage test fixtures to combine ICT and FCT. Wireless receptacles enable the wireless connection of test probes using a transfer PCB.

Test probes have a higher preload in comparison to standard test probes.
This initial higher spring force guarantees a secure contact at the same final load (the spring force is equal to that of the comparable standard test probe at working stroke).
Rotating test probes
Can provide a reliable alternative if contacting problems occur. A rotating movement during the stroke process scratches the surface to be contacted, thus insulating layers are securely penetrated.
Bead test probes
Are used to contact beads on PCBs. A variety of tip styles are available depending on the beads.
Fine-pitch test probes
Are used to contact very small test point in small grids. These are sometimes mounted without receptacles.

In addition to the classic ICT/FCT test probes without collars, the metric standard test probes stand out due to their stability and robustness and all feature a pronounced collar.
