DEK transfer heads reduce costs, waste materials

DEK has introduced the first of a new series of low volume ProFlow transfer heads that are claimed to reduce costs and waste materials, and at the same time improve accuracy and process control.

The heads are claimed to enhance the precision of high accuracy mass imaging using very small quantities of high value materials such as fine-particle, low-alpha solder pastes, and high gold-content compounds used to create grid arrays and other features in advanced packages such as CSPs and flip-chips.

Designed to achieve high accuracy and repeatability in processes requiring individual deposits <200mg, the transfer heads also reduce material pressure variation to achieve better metering accuracy. It also features a new locking mechanical interface that ensures the assembly is held perfectly perpendicular to the stencil surface at all times.

The first head to be introduced has a 180mm print width and features a 91cm? chamber that reduce material waste caused by deterioration. The head is filled from a syringe, rather than by replacing a cassette, and is compatible with any platform equipped to accept the standard ProFlow transfer head and featuring the DEK Software Controlled Air Regulator.
