Today, KINGSUN shares with you the common types and classifications of SMT mounters. 一、According to the feeding method, common ones include: 1.Tape Feeder 2.Tray Feeder 3.Tube Feeder 4.Stick Feeder 5.Special Vibration Feeder 二、According to the classification of electric and non electric, the common ones are electric feeder and mechanical feeder. Yamaha's SIGMA SMT machines are all electric feeders, while many of JUKI's feeder are mechanical feeders...... Regarding feeders related knowledge, KINGSUN share with you here , hoping to be helpful to you. More information about Products please Contact US at jenny@ksunsmt.com or visit www.ksunsmt.com .

The July 2006 implementation of ROHS exempted automotive applications from converting to lead free technology. Nine years later, all major OEM and Tier 1 automotive manufacturers have converted or are in the process of converting to lead free circuit assembly processing. Starting with SAC (SnAgCu) alloys as a baseline for lead free soldering, in the last years several specific alloys were developed in order to improve resistance to high temperature creep, vibration survival and the ability to withstand thermal cycling and thermal shock.The paper compares three different solder alloys and two flux chemistries in terms of void formation and mechanical / thermal fatigue properties. Void content and reliability data of the alloys will be presented and discussed in relation to the acceptance criteria of a Tier 1 /OEM automotive supplier. As a result, a ranking list will be presented considering the combined performance of the alloys. In order to analyze the void formation and mechanical behavior of different solder alloys and flux chemistry combinations, statistical methods are used.
