PCB, connectors BOM production classification and naming [design]
Update date：2012-10-15
PCB copy board in the production BOM, often found many connectors are never seen, can not blame our capacity is limited but there are too many different kinds of connectors is generally following class connector family (family) Example: connector sub-categories (sub-family) Example: circular connector type (type) Example: YB circular connector varieties (style) Example: YB3470 Specification (variant) in our electronic industry, connectors and switches, keyboards, etc. are collectively referred to as electric Jiechayuanjian, while the electric Jiechayuanjian relay collectively electromechanical components. Let's talk about product category connector connector products division although some confusion, but from a technical point of view, the the connector product categories are only two basic division approach: ① outline structure: circular and rectangular (cross-section) (2) operating frequency: low-frequency and high-frequency (3MHz to the community). Divided in accordance with the above, the coaxial connector is a circular, printed circuit connector is rectangular (Historically, the printed circuit connector is indeed isolated from the rectangular connector out of sui generis), currently popular The rectangular connector is trapezoidal in cross-section, similar to rectangular. Demarcation of boundaries for the low-frequency and high-frequency radio waves to 3MHz frequency allocation is consistent. As for other use, installation, special structure, special performance can also be divided into many different types, and often appear in publications and promotional materials manufacturers, but generally only in order to highlight the particular characteristics and uses, the basic classification remains does not exceed the above-mentioned principle of classification. Taking into account technological developments and the actual situation of the connector, its versatility and technical standards, the connector can be divided into the following categories (sub-categories): 1 low-frequency circular connector; ② rectangular connectors; ③ printed circuit the connector; ④ RF connector; ⑤ fiber optic connectors. Connector Model Naming The domestic take the following manner, and even in some industry standard makes provision GB as SJ2298-83 (printed circuit connector), SJ2297-83 (rectangular connector), SJ2459-84 ( ribbon cable connector), GB9538-88 (ribbon cable connector). Due to the growing diversity of the connector structure, in practice using a naming rules increasingly difficult to overlay a certain type connector. Another idea is a combination of Arabic numerals. The benefits of this approach is simple, easy to computer management and small logo print. International manufacturer of connectors are used in this way. Can be expected to reflect their own unique naming approach developed by various manufacturers will gradually replace the industry-wide unified regulations under the planned economic system by the way of some kind of naming.
Production BOM process, we need to continue to strengthen their own understanding of the material while also learning to the professional staff, so that of our BOM will be more professional.
