20100050430 | Method for Holding and Carrying Substrate - A part cartridge for a mounter device used in a mounting process for mounting electronic parts on a substrate by heating the substrate to a predetermined temperature after the electronic parts are mounted on the substrate put on a conveying carrier by the mounter device, comprising holding part holding the substrate in the state of being fitted to the conveying carrier, and a guide tape holding the holding part. The holding member is stored in the state of being wound together with the guide tape so that the holding part can be mounted on the conveying carrier by the mounter device. By this, a method of holding and carrying the substrate for mounting the holding part on the conveying carrier by using the mounter device can be adopted in the mounting process. The deflection of the substrate in reflow can be securely prevented while suppressing cost by effectively utilizing the existing mounting line and devices. | 03-04-2010 |
