Pin in Paste Connector Solutions for Efficient PCB Assembly
As electronic products become more compact and manufacturing processes more automated, efficient PCB assembly technologies play an increasingly important role. Pin in Paste (PiP) technology offers a proven solution for integrating through-hole connectors into automated SMT production processes, helping manufacturers improve efficiency while maintaining reliable mechanical and electrical performance.
Inelco develops and manufactures connectivity solutions optimized for Pin in Paste assembly processes. By combining connector expertise, advanced manufacturing knowledge and customized development capabilities, we support OEMs and design engineers in creating products that are optimized for both performance and manufacturability.
What Is Pin in Paste Technology?
Pin in Paste, often referred to as Through-Hole Reflow (THR), is an assembly method that allows through-hole components to be soldered during the standard SMT reflow process.
Instead of requiring a separate wave soldering operation, solder paste is applied directly into plated through-holes before component placement. During reflow, the solder forms reliable electrical and mechanical connections between the connector and the PCB.
This process enables manufacturers to combine the mechanical strength of through-hole technology with the efficiency of automated SMT production.
Why Use Pin in Paste Connector?
Modern electronic manufacturing demands shorter production cycles, greater automation and improved process consistency.
Pin in Paste technology helps address these requirements by:
- Reducing assembly complexity
- Supporting automated production
- Eliminating separate soldering processes
- Improving manufacturing efficiency
- Reducing handling requirements
- Supporting high-volume production
- Simplifying supply chain processes
- Improving process repeatability
For many OEMs, Pin in Paste technology has become an important design consideration during product development.
