Antistatic Mat and 30MHz Signal Generator

摘要

Good morning, children, now settle down. Today we will look at 'Electronics'. The Cat sat on the Anti-Static Mat... The use of such mats is common in industry, but not so among hobbyists and enthusiasts. The aim is to provide a safe environment for handling electronic components that are prone to damage by static electricity, CMOS devices particularly, and to avoid losing small parts. The mats don't need to be earthed as such, so long as the same electrostatic field strength conditions prevail across the bench area, but it is usual. Several versions are available, measuring about A3 paper size, 300 × 420mm, for about £12. Most have pockets, trays and ridges moulded in, and an all-round lip, to retain components and tools for instant use without rolling about or dropping on the floor. These mats are quite flexible, laying flat on the work surface, heatproof to 500°C and include several moulded-in trays, lidded and open, a partly ribbed or honeycomb surface and a larger area to the right for small tools, pens, etc,Fig.2.
