Induction Soldering Brass Connector

Induction Soldering Brass Connector In Solar Panel With IGBT Induction Heater

Objective Solder three brass connectors one at a time in a solar panelย junction box without affecting the components in the junctionย box
Material Solar panel junction box, brass connectors, solder wire
Temperature 700 ยบF (371 ยบC)
Frequency 344 kHz
Equipment โ€ข DW-UHF-6ย kW induction heating system, equipped with aย remote workhead containing one 1.0 ฮผF capacitor.
โ€ข An induction heating coil designed and developedย specifically for this application.
Process A three turn oval shaped helical coil is used to heat theย connectors. A piece of solder wire is placed onto the joint areaย and each joint is heated separately for 5 seconds to solder theย connector. The total process time is 15 seconds for the threeย joints.
Results/Benefits Induction heating provides:
โ€ข Pinpoint accuracy deliver heating only to joint; does notย affect surrounding components
โ€ข Localized heat produces neat and clean joints
โ€ข Produces high quality, repeatable results
โ€ข Even distribution of heating

Induction Soldering Brass Heating Exchanger

Induction Soldering Brass Heating Exchanger Of a Series Copper Pipeย 

Objective To solder a brass end cap to a series of copper tubes
Material Preassembled heat exchanger with copper tubes and 2 brassย end caps 2.36โ€ (60mm) OD, 0.08โ€ to 0.12โ€ (2 to 3mm) thick atย both ends, liquid solder
Temperature 302ยบF (150ยบC)
482ยบF (250ยบC)
Frequency 237kHz
Equipment โ€ข DW-UHF-20kW induction heating system, equipped with aย remote workhead containing one 1.0ฮผF capacitor
โ€ข An induction heating coil designed and developedย specifically for this application.
Process A dual four turn pancake coil is used to solder 2 brass caps perย cycle. Liquid solder is squirted onto the end cap and is heatedย for 18 seconds at 302ยบF (150ยบC) to burn off the flux. Then the
heat is increased to 482ยบF (250ยบC) for 15 seconds to solder theย parts.
Results
Induction heating provides:
โ€ข Even distribution of heating
โ€ข Compared to hot plate, induction heating is able to heat twoย parts in 30 seconds vs. one part in 60 seconds
โ€ข Increased production
โ€ข No discoloration with the slow heating process

Induction Soldering Brass Tube-Pipe

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″.
Frequency: 385 kHz

Induction Soldering Brass Rings

Induction Soldering Brass Rings With High Frequency IGBT Induction Heater

Objective: To heat 1 3/4″, 3″ and 6″ diameter brass slip rings and a sheathed copper wireย assembly to 3600 F for soldering within three (3) to six (6) seconds. Currentlyย production is accomplished by using a soldering iron and stick feeding rosinย cored solder. This process leaves unwanted solder on the side of the slip ringย where the soldering iron makes contact. The customer would like to see anย increase in joint quality without sacrificing time.
Material: 303 Brass Slip Rings of 1 3/4″, 3″ and 6″ diameters.ย Sheathed Copper Wire Assembly.
Resin Core Solder, 37% Pb, 63% Sn.
Temperature: 3750F
Application: Through laboratory testing, the DW-UHF-20kW output solid stateย induction power supply along with a unique four (4) turn “ear muff” type coilย produced the following results:
Times to reach 3750 F are as listed below:
– 1 3/4″ in 3 seconds
– 3″ in 3-4 seconds
– 6″ in 5 seconds
Adequate solder flow was observed producing a clean joint.
Solder preforms are recommended to speed up production.
Side loading was facilitated by the unique four (4) turn “ear muff” styleย coil.
Equipment: DW-UHF-20kW output solid state induction power supply includingย one (1) remote heat station containing one (1) 1.0 ฮผFcapacitor, a 4-20mAย input for fast ramp simulation, and a unique four (4) turn “ear muff” style coil.
