Rainbow promises to revolutionise HDI manufacture
A new method of producing High Density Interconnect (HDI) boards is being unveiled by Rainbow Technologies, a sister company to Teknek, the global leader in contact cleaning technologies. Traditional laser systems are expensive to buy and costly to operate. Not only that, their output is notoriously slow – most imaging only one side at a time.
Rainbow claims its new system will revolutionise printing of fine line detail, conductive tracks and resists for etching or plating down to 20 microns. The Rainbow process can produce 300 HDI panels (double sided) per hour. Running costs will be less than 25% of an LDI unit and will be more environmentally friendly. The unit itself is only six meters in length and consumes less than 7kW of power.
