Electronics manufacturer and training provider Solve Direct Electronics (SDE) has boosted its technological capacity by investing in the Seamark ZM-R62000 BGA rework and re-balling machine. The machine will enable the company to comply with the stringent ball grid array (BGA) placement requirements in South Africa.

A BGA is a type of chip carrier used for integrated circuits. BGA packages are used to permanently mount devices such as microprocessors. According to Neil Johnson, Director and founder of SDE, there is a severe shortage of professionals offering high-quality, reliable BGA placement and re-balling of lead-free and tin lead BGAs.

Neil Johnson Solve Direct Electronics“In order to replace defective components, reprogram firmware, or install a daughter board on complex or high-reel printed circuit board (PCB) assemblies, we wanted a rework system that combines ease-of-use with reliability and precision. These high-precision rework systems feature advanced optical alignment, automated component removal and replacement, and both top and bottom hot air for de-soldering and soldering,” Johnson explains.

“They are ideal, not only for delicate, heat-sensitive, and expensive surface mount devices (SMDs), such as BGAs, chip-scale packages (CSPs), and ultra-fine pitch quad flip packages (QFPs), but the stations can also be used for rework and repair of LED strips and boards.”

. The machine provides a liner slide function that establishes a X-, Y-, and Z-axis that can micro-adjust with rapid positioning and precision. It boasts a touch-screen controlled heating system with optical alignment for user-friendly operation that ensures positioning precision as well as time and temperature control systems that are industry-designed from various types of lead and lead-free profiles to ensure that soldering is reliable and effective.

The machine also has three independent heating areas from top to bottom, with pre-heating being infrared, and a powerful cross-flow fan to rapidly cool down the PCB, preventing deformation and ensuring natural solidification of solder connections.

The Seamark system will be used in SDE’s training, manufacturing and maintenance operations, allowing much greater precision in the positioning, heating and soldering of BGA components
