Hotbar Reflow Soldering

Vadd advanced software controlled Pulsed Heat Hot Bar Reflow Soldering System is a fully integrated, hot-bar system that utilizes a pulsed heat thermo technology for hot bar reflow soldering applications.

The Vadd equipment consists of ergonomically in house designed models with optional product handling features such as linear slides and rotary tables.

Hot bar bonding systems are “customizable” to suit the customer’s specific technical requirements via optional plug & play modules.

All of our systems are configured with full automatic process control with manual or semi automatic loading of parts.

All process parameters are embedded into the system, ensuring consistent process quality and operator independence offering maximized production output.

Our Pulsed Heat Reflow Soldering is a selective soldering process where two pre-fluxed, solder-coated parts are heated with a thermode to a sufficient temperature to melt the solder. After this the parts are cooled below the solidification temperature to form a permanent electro-mechanical bond.

The Vadd software controlled precision temperature control units provides targeted heating and precision temperature control for applications such as the connection of flexible circuits, ribbon cables, wires, single or dual sided edge connectors.

The temperature control systems includes:

• Closed-loop temperature and time control
• In excess of 60 various heating profiles
• Remote programming
• Thermocouples for process control and auxiliary monitoring that can be stored as quality assurance and control measures

Automatic Tip Soldering

Features

• Solder feed / reverse amount is adjustable in 0.1 mm increments
• Solder pre-heat / heat time is adjustable in 0.1 second increments
• Designed to minimize cycle time by using customized programs
• Specialized programs achieves much shorter tact/cycle time
• Temperature controller raises iron temperature to 350° in approximately 10 seconds
• Automatic temperature calibration function improves iron tip performance and stability
• High precision thermocouple is built into the Apex of the iron tip so minimal temperature drop can be detected and recovered quickly
• Innovative heater cartridge design is equipped with built-in thermocouple which provides excellent thermal efficiency with high-performance 130W heater
• Heater cartridge incorporates quick-change iron tip to meet end-user requirements for reducing consumable supply costs while maintaining superior performance

Crimp Force Monitoring

Vadd – creating the perfect connection.

During the crimping manufacturing process the force of the crimping is monitored and tested.

The test immediately determines whether or not a crimp is good based on predetermined force and height parameters.

Our advanced crimp force monitoring system consists of a load cell to measure crimp force, a triggering device that initiates reading of force measurement and a control unit to analyze the data.

The Vadd crimp force monitoring and test system is used on our automated crimping machines as well as our standard on crimp presses.

Crimp Height 

Prior to any crimp of terminals the crimp height is entered into the control unit.

Crimp height is determined either with a visual inspection system or manually with a micrometer, Determining dimensions from the crimp top and the crimp bottom.

This measurement is taken in the center of the crimp.

Once crimp height is determined, software in the control unit automatically calculates required crimp force and converts it into a curve over time that represents the perfect crimp.

With programming complete, the operator now teaches our advanced system to use the perfect crimp curve as a reference force. Each subsequent crimp is compared with this force. A bad crimp is one that deviates from the reference force.

In line crimp force measurement systems

Vadd has the option for in process crimp analysis via software for crimp curve analysis with possibility of statistical version storing measurement data to our mainframe computer.

Pull force measurement systems

Measures pullout forces up to 1000 N with accuracy of 0.03 N deliver precise and reproducible results. . This advanced sensitive maintains the pullout speed constant.

The tester can be connected via interface software to our mainframe computer for statistical data collection.

Crimp height measurement system

Integrated crimping height measurement system with automatic correction based on advanced software algorithms adjustment based on real measurement data.

The system corrects the crimp height automatically, eliminating the need for operators to make calculations in their heads and to adjust the crimping height manually by hand.

Significant cost advantages by reducing conversion time without compromising crimp quality.

ramp up is extremely short enabling our customers to meet vital time-to-market time frames.

Furthermore our in house software department, tooling and machinery division eliminates/reduces down time of production lines ensuring low cost, high productivity and yield reducing total cost.

All machinery and tools are on very excessive schedule preventive maintenance programs ensuring the perfect connection at all times.

Semi-Automatic Crimping

In our modern state-of-the-art production environment ensuring quality fast and reliability test of our crimp terminations is a competitive advantage with our “on the factory floor labs.”

Especially in the production of cable harnesses, reliability and high speed are of equal concerns.

Micrograph Inspection

A micrograph is a photo of a crimped terminal cross-section taken by a microscope. A micrograph inspection involves analyzing this photo to measure crimp height and width; determine whether or not the crimp is gas tight (no voids within the strands); and if and why there is terminal deformation.

Our fast and reliable micrograph analysis equipment saves costs and reduces rejects.

The micrograph laboratory equipment in our labs analyses and documents the quality of crimp connections by means of brilliant colour photographs. Micrographs are indispensable for the release of new crimp contacts and crimping tools.

Our track record proves that micrograph lab’s and equipment are a vital component for state-of-the-art quality engineering.

The system consists of equipment that provides vital data:

• Automatic cutting + polishing module
• Etching module and full size imaging for accurate cross-section analysis through
• Evaluation & Documentation integrated into our mainframe
