Machining printed circuit boards - cooling machining location with continuous or pulsed gas jets

摘要

Plastic and metal, partic. printed circuit boards are drilled or machined by a method in which the tool and the machining location are cooled by continuous or pulsed jets of gaseous N2, CO2, or O2, such that the cooling temp. of the medium is +10 deg.C to -150 deg.C. ADVANTAGE - Liquid cooling is not required, machining quality is improved.
