Component Packaging Evolution of SOP packaging

SOP (Small Out-Line Package) is a very common component form. One of the surface mount packages, the pins are led out from both sides of the package in a gull-wing shape (L-shape). The materials are plastic and ceramic. Started in the late 1970s. From the through-hole (PTH) type before the 1980s, the mainstream product was DIP (Dual In-Line Package), which progressed to the SOP (Small Out-Line Package) derived from SMT (Surface Mount Technology) technology in the 1980s , SOJ (Small Out-Line J-Lead), PLCC (Plastic Leaded Chip Carrier), and QFP (Quad Flat Package) packaging methods. After the IC functions and the number of I/O pins gradually increased, Intel took the lead in adopting the QFP packaging method in 1997. It has been updated to BGA (Ball Grid Array) packaging. In addition, the recent mainstream packaging methods include CSP (Chip Scale Package) and Flip Chip (flip chip).

From 1968 to 1969, Philips developed the Small Outline Package (SOP). Later, SOJ (J-pin small outline package), TSOP (thin small outline package), VSOP (very small outline package), SSOP (shrink SOP), TSSOP (thin shrunk SOP) and SOT (small outline package) were gradually derived. Outline Transistor), SOIC (Small Outline Integrated Circuit), etc.

Small out Line Package Application Range

The SOP package has a wide range of applications, and gradually derived SOJ (J-pin small outline package), TSOP (thin small outline package), VSOP (very small outline package), SSOP (shrink SOP), TSSOP (thin small outline package) Miniaturized SOP), SOT (Small Outline Transistor), SOIC (Small Outline Integrated Circuit), etc. have played a pivotal role in integrated circuits. The frequency generator like the main board is the SOP package.

The application of a specific SOP package type depends on its characteristics, such as pin count, pin pitch, size, and other features. Knowing the application of a specific SOP package type can help designers select the most appropriate package for their electronic devices.
