Induction Soldering Brass To Copper

Induction Soldering Brass To Copper With IGBT High Frequency Heating Equipment

Objective To heat brass and copper for soldering application on medicalย equipment
Material Brass ring, brass and copper pieces 5.11โ€ (130mm) long, 4.3โ€ย (110mm) OD & 0.3โ€ (7mm) at thickest point and solder rings
Temperature 392 ยบF (200 ยบC)
Frequency 306 kHz
Equipment โ€ข DW-UHF-10ย kW induction heating system, equipped with aย remote workhead containing two 0.33ฮผF capacitors for aย total of 0.66ฮผF
โ€ข An induction heating coil designed and developedย specifically for this application.
Process This process is completed in two steps that use a 3 turn helicalย coil. The first process is to solder the brass ring to the copperย piece which takes 85 seconds. The second step is to solder aย large brass piece to the first assembly. This process takes 50ย seconds for a total process time of two minutes 15 seconds.
Results/Benefits Induction heating provides:
โ€ข Hands-free heating that involves no operator skill forย manufacturing
โ€ข Even distribution of heating
โ€ข Faster process time, current process takes 5 minutes
โ€ข Consistency by using solder rings

Induction Soldering Brass Tube-Pipe-Tubing With RF Soldering Heating System

Objective: Soldering two brass tubes measuring 3/4″ and 1/4″ together for use as cellularย phone antennas. The lengths of tubes range from four (4) feet to twelve (12)ย feet, and must be soldered along the axial side. The joint is to be made usingย 60/40 Tin Lead Solder and Kestor Rosin paste flux.
Material: Brass Tubes measuring 3/4″ and 1/4″ย 60/40 Tin Lead Solder
Kestor Rosin Flux
Temperature: 3750F
Application: Through the use of the the DW-UHF-40KW output solid state inductionย power supply along with a unique five (5) turn 12″ long channel coil, the followingย results were achieved:
3750 F was reached and the solder flowed after a heating period of 35ย seconds.
A production rate of 24″ per minute was determined to be adequate.
A quality solder fillet was observed after heating and cooling
Equipment: DW-UHF-40kW output solid state induction power supply includingย one (1) remote heat station containing two (2) capacitors, and a unique fiveย (5) turn channel coil made from 3/16″ copper tubing and measuring 1 1/4″ byย 12″.
