摘　　要：Bonding with adhesives is an important technique for building up hybridmicrosystems. Some adhesives are tested with capillary dispensing system for microassembly, andvolume of droplets less than 10 nl with good repeatability can be acquired. 1-part UV curingadhesive hardens rapidly and is suitable for bonding of transparent microparts. Light-activatedadhesive starts the curing process in an adjustable short period of time after the radiation ofvisible light, and thus suits bonding of non-transparent microparts. A method is proposed forbonding the guides of a miniature linear motor being developed by collaborate research center 516(SFB516) in Germany. With the method high assembly accuracy in the vertical direction can beguaranteed. By making small grooves on the stator for containing adhesive, the deterioration of theaccuracy due to the thickness of adhesive layer can be avoided. The criteria on deciding the size ofthe groove are given and analyzed. Vision based inspection method is introduced for automaticassembly of the guides. The dispensing volume and position of dispensed adhesive droplets can bedetected for ensuring the bonding quality.Bonding with adhesives is an important technique for building up hybridmicrosystems.
