Popularize the SMT processing process in Yantai

As a pioneer in the Yantai circuit board and SMT (Surface Mount Technology) placement processing industries, Yantai Zhan'ge Electronics Co., Ltd. has always been committed to the innovation and development of new products. We consistently prioritize customer needs as the starting point for our production and strive to repay our customers with high-quality products, earning us the trust of a broad customer base. Below, the editor from Zhan'ge Electronics will provide you with an overview of the SMT processing workflow, which we believe will be informative:

1. Screen Printing: This step involves transferring solder paste or adhesive onto the pads of the PCB (Printed Circuit Board) through a stencil, preparing for the soldering of components. The commonly used equipment is a screen printer (silk screen printing machine), located at the forefront of the SMT production line.

2. Dispensing: This process involves applying adhesive drops to specific locations on the PCB to secure components in place. The equipment used is a dispenser, positioned either at the beginning of the SMT production line or after inspection equipment.

3. Placement: This function involves accurately installing surface-mount components onto predetermined positions on the PCB. The required equipment is a placement machine (pick-and-place machine), located after the screen printer in the SMT production line.

4. Curing: This step melts the adhesive, thereby firmly bonding the surface-mount components to the PCB. The equipment needed is a curing oven, located after the placement machine in the SMT production line.

5. Reflow Soldering: This process melts the solder paste, firmly bonding the surface-mount components to the PCB. The required equipment is a reflow oven, located after the placement machine in the SMT production line.

6. Cleaning: This step removes harmful soldering residues, such as flux, from the assembled PCB. The equipment used is a cleaning machine, which can be positioned either in-line or off-line, depending on the requirements.

7. Inspection: This function involves inspecting the assembled PCB for soldering quality and assembly quality. The equipment required includes magnifying glasses, microscopes, in-circuit testers (ICT), flying probe testers, automated optical inspection (AOI) systems, X-ray inspection systems, and functional testers. The inspection equipment can be placed at appropriate locations along the production line based on inspection needs.

8. Rework: This step involves repairing PCBs that have failed inspection. Common production tools include soldering irons and rework stations. These can be positioned anywhere along the production line as needed.

The above is a detailed explanation of the SMT processing workflow provided by Yantai Zhan'ge Electronics. With our professional SMT processing line, technical expertise, and dedicated service, we produce high-quality circuit boards. Earlier this year, Yantai Zhan'ge Electronics Co., Ltd. was interviewed by Yantai News Comprehensive Channel, further enhancing our reputation.
