At POE, we understand the importance of delivering high-quality and efficient services to our clients. One crucial aspect of PCB manufacturing is the Surface Mount Technology (SMT) assembly process. To ensure accurate and consistent placement of electronic components on a PCB, we provide specialized tooling and SMT stencil services.
Tooling
We offer a range of tooling equipment to support the SMT assembly process. Our tooling equipment includes pick and place machines, soldering machines, and inspection equipment.
Pick and Place Machines
Our pick and place machines are essential to the SMT assembly process, as they ensure precise and consistent placement of electronic components on a PCB. We offer a range of pick and place machines, including manual, semi-automatic, and fully automatic models. Our pick and place machines use vacuum suction to pick up components and place them onto the PCB with accuracy and precision.
Our manual pick and place machines are ideal for small-scale production runs, as they allow for greater flexibility and control over the assembly process. Our semi-automatic pick and place machines offer a balance between manual and fully automatic machines, as they require minimal operator intervention while still offering greater flexibility. Our fully automatic pick and place machines are ideal for large-scale production runs, as they can place components on a PCB at a high speed and with consistent accuracy.
Soldering Machines
Our soldering machines are used to attach components to the PCB. We offer a range of soldering machines, including reflow ovens, wave soldering machines, and selective soldering machines.
Reflow ovens are used to solder surface mount components onto a PCB. This is done by heating the PCB to a specific temperature to melt the solder paste and create a connection between the components and the PCB.
Wave soldering machines are used to solder through-hole components onto a PCB. This is done by passing the PCB over a wave of molten solder, which creates a connection between the components and the PCB.
Selective soldering machines are used to solder specific areas of a PCB. This is done by using a robotic arm to apply solder to specific areas of the board.
Inspection Equipment
Our inspection equipment is used to check the quality of the SMT assembly. We offer a range of inspection equipment, including automated optical inspection (AOI) machines, X-ray machines, and flying probe testers.
AOI machines are used to detect defects, such as missing components, misplaced components, and soldering defects. This is done by taking a high-resolution image of the PCB and comparing it to a reference image.
X-ray machines are used to detect defects that are not visible to the naked eye, such as voids in the solder joints. This is done by passing X-rays through the PCB and detecting any changes in the radiation that pass through the board.
Flying probe testers are used to test the electrical connectivity of a PCB. This is done by using a series of probes to test each component on the board.
SMT Stencil Services
We also offer SMT stencil services. SMT stencils are thin sheets of metal with cutouts that correspond to the locations of components on the PCB. These stencils are placed over the PCB and solder paste is applied to the cutouts. When the stencil is removed, the solder paste remains on the PCB in the locations where components will be placed.
SMT Stencil Design
Our SMT stencil services use computer-aided design (CAD) software to create a stencil design that matches the PCB layout. Our experienced engineers work with our clients to ensure that the stencil design meets their specific requirements. We use the latest CAD software to ensure that the stencil design is accurate and meets industry standards.
SMT Stencil Manufacturing
Once the stencil design has been finalized, we manufacture the stencil using laser cutting or chemical etching techniques. Our manufacturing process ensures that the stencil is made to a high standard and meets the client's specific requirements.
Benefits of SMT Stencil Services
The use of SMT stencils in the assembly process has several benefits. First, it improves the accuracy and consistency of solder paste application. This leads to a reduction in defects and an increase in the quality of the finished product. Second, it reduces the amount of solder paste required for the assembly process. This leads to a reduction in material costs and waste. Finally, it increases the speed of the assembly process. Automated machines can applysolder paste to the PCB much faster using stencils than by manual labor.We understand the importance of providing quality and efficient service to our clients. Our specialty tooling and SMT stencil services are critical to the SMT assembly process, ensuring accurate and consistent placement of electronic components on PCBs. The use of specialized tools increases the accuracy and consistency of component placement, increases the speed of the assembly process, and reduces labor costs.
