New Full Automatic Dip Welding Double-head Selective Soldering Machine SMT PCB Lead-Free Wave Flux Sprayer System

The **New Full Automatic DIP Welding Double-Head Selective Soldering Machine (Model 400TW)** from **Shenzhen TY Electronic Technology Co., Ltd.** is an automated PCB soldering system designed for **through-hole (DIP) component assembly and selective soldering applications**. The machine is equipped with a **double-head soldering configuration** and a **wave flux spraying system**, enabling controlled and targeted soldering of PCB components. The machine is designed for **lead-free soldering**, making it suitable for modern electronics manufacturing processes that require lead-free production. Its selective soldering capability allows solder to be applied to specific areas of a PCB rather than processing the entire board through a conventional wave, which can help reduce unnecessary solder consumption and improve process control. The equipment features an enclosed industrial structure with automated movement and positioning mechanisms. The internal arrangement shown in the product image includes soldering assemblies, PCB support/positioning components, mechanical drives, and a flux application system. The automated configuration is intended to provide consistent soldering performance while reducing manual intervention. The **double-head design** can support efficient processing by providing multiple soldering operations within the same production cycle. This makes the equipment suitable for applications where PCBs contain a combination of surface-mounted and through-hole components and require precise soldering at selected locations. The machine can be used in **PCB assembly plants, electronics manufacturing facilities, contract manufacturing units, and industrial production lines**. It is particularly relevant for manufacturers looking to automate DIP soldering while maintaining controlled solder application. According to the displayed listing, the machine has a **model number of 400TW**, a listed price of approximately **US$3,000**, and a **minimum order quantity of one set**. Shipping charges and delivery schedules are negotiated separately with the supplier. Overall, the 400TW provides an automated solution for **lead-free DIP selective soldering**, combining double-head soldering, flux spraying, and automated PCB processing for electronics manufacturing applications.
