Header types are characterized by pitch (the distance between the center of one pin to the the center of the next pin). Common header pitches are:

Pins are numbered (counted) from the bottom of the row to the top, then picked up at the bottom of the next row. For male headers, start on the left and for female headers, start on the right. For headers attached to ribbon cables, the pins are numbered linearly across the cable. In a two-row header, pins in one row have odd numbers and pins in the other row have even numbers.

NorComp’s 2663/2664 Series features 2 mm header single row/dual row with straight pin header. The .079″ spacing saves valuable space. The series is available in a variety of pin counts and minimizes PCB stacking heights.

Pin headers are sold in long strips, typically with 36, 40, or 50 pins. The strips can be cut to the required length (number of pins). The availability of various pin lengths minimizes labor during PCB assembly.

Pin headers are typically through-hole devices (THD). That is, the pins are inserted through holes drilled in the PCB and soldered on the opposite side. However, some headers are surface mount devices (SMD). In this case, the pins are bent 90° and mounted (soldered) directly to the surface of the PCB.

A pin header, or header, is a male connector with one or two rows of metal pins attached to a plastic base. Pin headers with more than two rows are available from some manufacturers. The pins are spaced in uniform intervals (commonly 2.54 mm or 0.1 inch apart) but many spacings are available depending on the application. The female counterpart is sometimes referred to as a female socket header.

Headers are also defined by the number of pins wide by the number of rows. For example, a header that has two rows of eight pins is identified as an 8×2 header.

The original pin header was manufactured by Berg Electronics Corporation (now part of Amphenol) and, as a result, pin headers are sometimes called Berg connectors. Today, they are manufactured by many companies.

COG is an advanced technology to adhere IC chips onto glass(LCD). By Flip Chip technology, a gold bumped IC chip is connected to the ITO of LCD panels with ACF as a media. When this technology is applied to LCD panels due to the circuit board being glass, it is so-called Chip on Glass (COG), and bonding of the flexible printed circuit(FPC) and glass(LCD) is called FOG(Film On Glass). COG would be produced by means of wafer to tray. After LCD panel module factory acquires IC, the gold bump of the IC is bonded to the circuit board of LCD panels with ACF, then use ACF bonding with FPC, this production is called FOG process.
