An Austrian refugee in London, Eisler made this radio in 1942, following on from initial experiments in 1936. At the time, it was usual to interconnect all components in electronic goods with hand-soldered wires, a method of manufacture which did not lend itself to any high degree of automation. First applied in proximity fuses for anti-aircraft missiles, PCBs have subsequently found near universal application in electronic goods, yielding highly miniaturised devices which can be mass produced.

What is the lifetime of printed circuit board?

Depends on the material it's constructed from, the application for which it's being used and the atmospherics to which it's exposed. I have printed circuit boards from the very first model of an RCA transistor radio made in 1957 and the circuit board as well as the electronics still work.

How do you grind up a circuit board?

To grind a circuit board, the individual electronic components have to be removed first. The circuit board is usually ground industrially and recycled for a number of functions.

What are the four steps for correctly soldering components to a printed circuit board?

1. Remove the soldering iron from the holder and wipe the tip on a sponge. 2. Heat the joint to be soldered. 3. Apply solder to the joint. 4. Apply a small bit of solder to the tip of the soldering iron and return it to the holder.

How do you replace the wiper motor circuit board?

This is really an easy fix. The wiper motor assembly is on the firewall, just right of center. The wiring can be unplugged before the circuit board is removed, or afterward. I found it easier to unplug it after the circuit board was removed. There is a flat cover that is held on with three torx screws (T20). Remove those screws and remove the cover. The circuit board will now be visible. Remove the circuit board by grasping the wiring connecter and gently pulling it towards the front of the vehicle. When the circuit board has fallen free, unplug it from the wiring harness if you haven't already done so. The solder joints that connect the wiring socket to the board were bad on my board. I just resoldered those and re-installed the circuit board. I did get an entire wiper motor assembly, which included the board, from a salvage yard for $40. I didn't even use it. Excellent answer! My wipers would not start without getting out and helping, then they might or might not continue running after a few wipes. When switched on and not running, module would produce buzzing sound. Followed directions above, and even though the three pins joining the wiring harness plug to the circuit board looked properly soldered, carefully re-soldered making sure to have good solder contact to printed circuit strips. In my case this worked like a charm, and judging from the number of postings for this fix, it seems to be a common problem with this board. It would seem to be a good first step unless there are other obvious signs of failure.

What organization developed the first national building code?

How is current measured in a series circuit?

Current is measured in a series circuit by the use of a multimeter. First, the power source must be attached to the circuit board. The board is attached to the multimeter, then that is attached back to the power source.AnswerCurrent is measured either with an ammeter, or with a multimeter set to measure current. The instrument must be connected in series with the other components in the circuit.
