1. Most SMT chip components are reflow soldered, while through-hole components are wave soldered, though it is not a hard and fast rule.
2. In through-hole PCB assembly technology, the board is wave soldered to form a strong solder joint even when the component is inserted into the drilled hole. Usually, through-hole components are inserted manually.
3. For SMT components, solder paste is applied directly to the pads, holding the leads of the component in one position.
4. When the PCB is passed through the special reflow oven, the solder paste is reflowed, forming a solid solder joint.
5. If you are using a hybrid type, you will need to utilize both wave soldering and reflow soldering.
6. There are ready automatic pick-and-place machines available that can reliably handle the various components.
1. The Benefits of SMT and Through-Hole
2. Let’s delve into why SMT machining types are frequently utilized:
3. Size: SMT components are inherently small or miniature, obviating the need for drilling. This lends a clean and attractive appearance, particularly pertinent in the era of shrinking electronics board dimensions.
4. Availability: Presently, SMT has supplanted through-hole components. These diminutive components are replacing resistors, capacitors, and other through-hole counterparts, increasingly dominating PCBA patching.
5. Performance: Integration of smaller components in Surface Mount Devices (SMD) facilitates shorter transmission paths for electrical signals, thereby reducing signal flight time.
6. Cost-effectiveness: SMT parts often boast a lower price tag compared to through-hole counterparts. However, it’s worthwhile to briefly explore the merits of through-hole parts.
7. Availability: When necessitating larger components for high-power applications, sourcing an SMT equivalent might pose challenges. Through-hole parts are readily accessible in such scenarios.
8. Strength: SMT solder joints may succumb to breakage under constant pressure. Hence, components like connectors, switches, and other interface elements necessitate the robustness afforded by solder leads anchored into drilled holes.
9. Power: SMT proves suboptimal for high-power circuits due to the difficulty in achieving robust solder joints. Conversely, through-hole technology offers superior mechanical strength conducive to thermal stability, high voltage tolerance, and mechanical integrity.
