Surface mount components are being used extensively these days. Most of the electronic gadgets that we use, such as mobile phones, digital cameras, CD players, LCDs, etc. use surface mount components extensively. A comprehensivetutorial on SMT components is available at Tutorialsweb.com. The contents are given briefly below:
PassiveComponents: Surface mount passive components including resistors, capacitors, and inductors were discussed.
Active Components: Examples of surface mount active components are diodes, Transistors, and ICs. ICs can be further divided in to the following categories:
- SOICs (Small Outline Integrated Circuits)
- SSOP (Shrink Small Outline Package)
- TSSOP (Thin Shrink Small Outline Package)
- SOJ (Small Outline J-leaded package) and others
Surface Mount Integrated circuits that are available in Quad-in-Line include the following:
- QFP (Quad Flat Pack)
- PGA (Pin Grid Array)
- BGA (Ball Grid Array)
Chip-on-Board (COB) is a special IC that uses bare die for bonding on to the PCB. It is commonly used where very high component density is required, and where lead lengths may affect the electrical parameters and thurs the functioning of the circuit.
