- 1. PCBA assembly process flow Single Side Surface Mounting Single sided plug-in mounting Double sided surface mounting Single sided mix assembly Double sided mix assembly @2013 Agile Circuit Co., Ltd All Right Reserved ||www.agipcb.com Internal usage only
- 2. Single Side Surface Mounting Solder printing SMD parts Reflow soldering Solder paste——Reflow Soldering Simple Fast Easy Single sided plug-in mounting Forming THT parts Wave soldering Wave soldering Simple Fast Easy Forming is the most inefficient work in the wave soldering ， and it may cause electrostatic damage and increase mistake probability, also may delay the delivery time the same time. @2013 Agile Circuit Co., Ltd All Right Reserved ||www.agipcb.com Internal usage only
- 3. Double sided surface mounting B side Solder paste printing SMD parts Reflow soldering Flipping A side Solder paste printing SMD parts Reflow soldering flipping To make full use of PCB space, smaller the mounting area and improve efficiency, A side usually is layout with big IC components and B side mainly chip components. @2013 Agile Circuit Co., Ltd All Right Reserved ||www.agipcb.com 3 Internal usage only
- 4. Single sided mix assembly Solder paste printing Surface mounted parts Reflow soldering THT components Wave soldering PCBA assembly with second heating, higher efficiency Remark: If THT components quantity is small, could use reflow soldering and hand welding. @2013 Agile Circuit Co., Ltd All Right Reserved ||www.agipcb.com Internal usage only
