The heat sensitive parts in the machine must be modified, or measures must be taken to prevent heat transfer to these parts. The design of the furnace must be changed to meet such requirements. for lead-free solder or non eutectic solder (used for BGA, double-sided plates, etc.), higher furnace temperature is required, These new processes usually require the temperature in the reflux zone to reach 3500c-4000c. Many furnaces used now are designed to have a high operating temperature of not more than 3000 C. The industry has applied the process as soon as possible, and the time has been saved. The two machines, the eC-stencil-mate solder-paste printer and eC-reflow-mate reflow oven, have been developed exclusively for Eurocircuits by a team of Dutch. However, the industry must probably go through this painful learning period to solve the problems encountered. Nitrogen protection can partially eliminate oxidation and damage to PCB due to temperature increase. At present, many substitutes developed generally have a melting point temperature of about 40C higher than that of tin lead alloy, which means that reflow soldering must be carried out at a higher temperature. Reliable and economical lead-free solders are being developed. Although the lead used in the electronic industry is very small, less than 1% of the total consumption, it is also prohibited and will be phased out in the next few years.
Processing space: 380 mm (W) x 310 mm (D) x 100 mm (H) can handle the mounting of even large pieces of work.
This is mainly caused by the characteristics of the solder alloy and the different fluxes.įor the sake of environmental protection, lead will be strictly restricted in the 21st century. reflow soldering machine MP2 automatic high-speed vacuum A mass-production unit with two-chambered specifications, allowing for separate cooling and heating. In terms of process, the welding process has the greatest impact. The change in material, especially in solder, is the largest. With the development of environmental protection, people pay more and more attention to lead-free technology. Early reflow solders were all made of lead containing materials. A mass-production unit with two-chambered specifications, allowing for separate cooling and heating.

Temperature control range: Room temperature~350℃ Temperature control method: PID control+ SSR drive Main parameter of reflow soldering machine It has been applied in almost all fields of electronic products. With the development of the entire technology of SMT becoming more and more perfect, and the emergence of a variety of chip components (SMC) and mount devices (SMD), the reflow soldering process technology and equipment as part of the placement technology has also been developed accordingly, and its application is becoming more and more extensive. At first, only the reflow soldering process was used in the assembly of hybrid integrated circuit boards, and most of the components to be assembled and soldered were chip capacitors, chip inductors, mounted transistors and diodes. But no matter automatic line or semiautomatic line all using same reflow oven soldering machine.ĭue to the continuous miniaturization of electronic product PCB boards, chip components appear, and traditional soldering methods can no longer meet the needs.
The big difference between automatic line and semiautomatic line is the stencil printer machine, Automatic stencil printer machine is send board automatically, save labor.
