What is an energy meter ?
Device to measure electrical consumption in units.
Electric meters are typically calibrated in billing units, the most common one being the kilowatt hour.
Production steps :
PCB Manufacturing steps
Commercial production methods
Hobbyist prototype
Advantages of using pcb’s
Saving of time
Saving of space on the circuit board
Saving of wires
Low cost
Reliablity
Automation
Disadvantages of using pcb’s
Only little current can flow between the components as the copper tracks are very thin.
Soldering requires extreme precaution as it can damage the copper tracks.
Design and fabrication of pcb’s
Preprocessing
Photolithography
Appliying photoresist
Exposure to UV
Development
Etching
Stripping
Drilling
Bareboard Testing
Soldering
What is smt ?
SMT stands for Surface Mount Technology.
One of the latest trend in the Electronics industry.
It is a technology in which surface mount components are directly mounted on the surface of Printed Circuit Board.
conclusion
A brief knowledge about the energy meters.
Knowledge about single phase & three phase meters.
Testing of Meters.
