Wenesco Wave Type Re-Work
Concept 5, Concept 6
This Concept 5 and This Concept 6 wave type re-work systems are designed for precision removal of long connectors from multilayer PCBs.
This Concept 5 removes connectors up to 6 inches long, while This Concept 6 handles connectors up to 14 inches long with controlled solder flow and localized heating for sensitive electronic assemblies.
Both systems feature a ceramic-coated interior for standard or lead-free alloys, a digital thermostat maintaining temperatures up to 350°C (662°F), and a variable speed dual-mode pump for a dross-free wave.
Additional features include a radiant preheater, slide rails, laser-guided nozzle positioning, footswitch-activated timer control, stainless steel housing with adjustable feet, one standard nozzle, and an optional blow-out hand gun for clearing holes after component removal.
Wenesco welcomes your inquiry regarding other sizes and shapes.
| MODEL | MAX NOZZLE SIZE | POWER | PREHEATER | MAX PCB | SOLDER LBS |
|---|---|---|---|---|---|
| CONCEPT 5 | 6 X 1 IN | 2000W - 120 OR 240 V | 6 X 6 IN | 8 X 6 | 65 |
| CONCEPT 6 | 14 X 2 IN | 3000W - 240V | 12 X 18 IN | 12 X 18 | 130 |
The integrated radiant preheater reduces flow cycle time and lowers overall temperature requirements when re-working multilayer PCBs. Preheating activates flux before soldering and minimizes thermal shock that can cause warpage, thru-hole damage, or delamination, while the precision mini-wave nozzle directs controlled solder flow to the lead pattern with minimal heat transfer to surrounding components.
Frequently Asked Questions
What is the difference between This Concept 5 and This Concept 6?
This Concept 5 is designed to remove connectors up to 6 inches long, while This Concept 6 supports connectors up to 14 inches long for larger PCB assemblies.
What types of PCBs can these systems process?
These wave type re-work systems are designed for multilayer printed circuit boards commonly used in electronics manufacturing, aerospace, defense, and industrial applications.
Why is the radiant preheater important in PCB re-work?
The radiant preheater reduces thermal shock by gradually heating the PCB before solder flow begins. This helps prevent board warpage, thru-hole damage, and delamination during component removal.
Can the systems operate with lead-free solder alloys?
Yes. The ceramic-coated interior is compatible with both standard and lead-free solder alloys used in modern PCB manufacturing processes.
How does the solder removal process work?
The component is positioned above a mini-wave nozzle matched to the lead pattern. Controlled solder flow heats the thru-hole connections, allowing the component to be removed while minimizing heat transfer to surrounding areas.
