Proven Through Hole Assembly Services
Through hole technology remains essential for applications requiring superior mechanical strength, thermal performance, and long-term reliability in harsh environments. Our through hole assembly services encompass the complete spectrum of through-hole mounting solutions, from prototype development through high-volume production runs.
Four Automated Through Hole Processes
- Jumper Wire Insertion Our J-STD certified solderers handle critical jumper wire placement for circuit continuity, board modifications, and defect corrections. This process ensures electrical integrity between connection points while maintaining the highest quality standards.
- DIP Insertion Dual Inline Package insertion utilizes both manual and automatic machines for precise component placement. Our automated DIP insertion machines provide programmable loading and placement, while manual systems offer flexibility for specialized requirements.
- Axial Component Sequencing Pre-sequencing axial components on carrier tapes reduces assembly time and minimizes errors. This process aligns components with your PCB board assembly specifications, boosting production efficiency while reducing costly rework.
- Axial Insertion Automated axial insertion takes pre-sequenced components through precise cutting, lead forming, and insertion processes. Components transfer from sequence chains to insertion chains, where insertion heads cut leads to proper length, bend them 90 degrees, and insert them into boards with clinch assembly.
