• PLCs and servo motors help control the machine better. They also make it work faster and smoother.

• Cleaning and taking care of the machine stops clogs. This helps the machine work well all the time.

• You can change the settings for different coil types. This lets the machine work for many industries.

1. Coil Placement

When you use an Automatic Coil Soldering Machine, the first thing to do is coil placement. This step is important for good and fast soldering. You must load and line up each coil the right way before soldering starts.

Loading

Manual vs. Auto

There are two main ways to load coils onto the machine:

1. Manual Loading:
   You put each coil on the machine by hand. This way is good for small jobs or special coils. Manual loading lets you control the process, but it can be slow. It also means people might make mistakes.

2. Automatic Loading:
   The machine uses robotic arms or feeders to place coils. Automatic loading is faster and more steady. It helps stop mistakes and keeps work moving, especially when making many coils.

Tip: Automatic loading works best for big factories. It keeps the work going and helps stop mistakes from being tired.

Positioning

After loading, you need to make sure each coil is in the right spot. The machine uses holders to keep the coil still. Good positioning stops the coil from moving during soldering. This is important for strong and safe joints.

Alignment

Sensors

Sensors are very important for coil alignment. They check if each coil is in the right place before soldering. Sensors can find even tiny mistakes in placement. This helps you avoid problems. In electronics, robots use sensors to handle and check small parts. After placing, sensors make sure everything lines up. This helps with quality and cuts down on mistakes.

Guides

Mechanical guides help sensors keep coils lined up. Guides move the coil into the right spot for soldering. You get help from both the guides and the sensors. This teamwork makes sure every coil is in the center and ready for the next step.

Note: The core’s stability and accuracy are very important for coil alignment. If the core is not right, the wire can wind unevenly and cause stress. You should check the core carefully before winding. Bad core alignment often happens when the core is not centered. Doing regular checks and fixes helps keep all parts safe and lined up.

Many machines use tables that turn and have many stations, like a 6-station table. This setup lets you load, line up, solder, and unload coils in a loop. You save time and work better because each station does a different job.

2. Solder Application

The solder application process in an Automatic Coil Soldering Machine has many careful steps. You need to know how the machine feeds solder, moves wire, and uses the nozzle. These steps help make strong and safe joints.

Solder Feeding

Solder Types

You can use different solder types in these machines. Many factories pick lead-free solder because of strict rules and health worries. The table below shows if solder types work with the IS-800TW Model:

Lead-free solder helps you follow RoHS rules. It also lowers dangerous materials in electronics. This choice makes health risks from lead smaller. Groups like the WHO say lead is a big health problem.

Wire Handling

Wire handling is very important for good solder joints. The machine uses a short feeder unit and a wire pull system. This keeps the feeder close to the soldering tip. It helps make sure the wire goes in the right spot. You get better solder joints because the system:

• Uses a tin-breaking automatic solder wire feeding system to make welding better.

• Feeds solder wire with accuracy up to 0.1mm.

• Lowers the chance of dirt by using less human touch.

• Makes electrical contact more reliable.

Nozzle Control

Temperature

Keeping the right temperature is important for good soldering. The Automatic Coil Soldering Machine uses digital controllers and smart sensors. These keep the soldering tip at the best temperature. You do not need to set the temperature yourself. This system:

• Keeps the temperature steady for the best soldering.

• Uses sensors or thermocouples to hold the tip steady.

• Makes soldering iron tips last longer by stopping big temperature changes.

Maintenance

You need to keep the nozzle clean and working well. Cleaning stops clogs and helps solder flow smoothly. The machine will tell you when it needs cleaning or new parts. Taking care of the machine helps you avoid stopping work and keeps things running well.

Tip: Always follow the cleaning schedule from the maker. Clean nozzles and steady temperature help make better solder joints and keep the machine working longer.

3. Heating Process

When you get to the heating step, technology helps a lot. The Automatic Coil Soldering Machine uses special heating ways to make strong joints. There are two main heating ways: induction and resistance.

Methods

Induction

• Induction heating uses electromagnetic fields to warm metal parts fast and evenly.

• You can solder or braze with alloys like lead, tin, or zinc.

• This way heats the whole joint to the right temperature for good bonds.

• Induction heating can also heat treat parts, making them hard or tough much faster than old ways.

Tip: Induction heating is great when you need exact and repeatable results. It also lowers the chance of surface oxidation because it heats up fast.

Resistance

• Resistance heating sends electric current through the coil or joint.

• The metal gets hot because it resists the current.

• This way is easy to set up, but it can heat unevenly, especially with tricky shapes.

• Longer heating times can cause more oxidation and may hurt the final quality.

Here is a quick look at both ways:

• Induction heating gives you more control and saves more energy.

• Resistance heating may not always give the same quality, especially for hard designs.

Soldering

Timing

You must control how long the heating lasts. The machine sets the right time for each joint. This stops overheating or underheating. Good timing lets the solder flow well and stick the coil tight. If you go too fast, joints can be weak. If you wait too long, the coil can get hurt or oxidize.

Pressure

Using the right pressure is as important as timing. The Automatic Coil Soldering Machine uses exact actuators to press the coil and solder together. You get a strong bond without breaking small parts. Too much pressure can bend the coil. Too little pressure can make a weak bond.

Note: Always check the machine’s timing and pressure settings. Even small changes can really affect how good your soldered coils are.

4. Inspection

Inspection is very important for good results from your Automatic Coil Soldering Machine. Automated systems check every coil for problems. They make sure each solder joint meets strict rules.

Automated Checks

Cameras

You use cameras to look at coils. Automated Optical Inspection (AOI) takes clear pictures of each coil and joint. AOI finds problems like open circuits and solder bridges. It also spots parts that are not lined up. AOI works quickly and finds small mistakes you might miss.

Automated X-Ray Inspection (AXI) looks inside coils. AXI checks solder joints that cameras cannot see. It is useful for parts under things like BGAs. You get a full look at hidden joints. This makes sure every connection is strong.

• AOI finds soldering problems, open circuits, and bridges by looking at pictures.

• AXI checks hidden solder joints to make sure connections are good.

Testing

Machines test each coil to see if it works. They measure resistance and check if electricity flows. If a coil fails, the system marks it for review. You also check for thermal shock and make sure wires are not damaged. Inspections happen before coatings go on. This helps you find problems early.

Defect Handling

Rework

If you find a problem, you decide if it can be fixed. The machine uses scores to sort defects:

If the score is in the middle, you check the coil by hand. You can fix coils that do not meet standards. This helps improve quality and waste less.

Rejects

Coils with high scores get rejected. The machine puts these coils in a reject bin. You keep track of rejected coils and use feedback to train the system. Over time, you see fewer rejects and better repairs.

Common Defects You Might Find:

• Solder balls

• Solder beading

• Bridging

• Open or not enough solder

• Tombstoning

• Unmelted paste

• Too much filet

• Slump

• Dewetting

• Disturbed joint

• Orange skinning

Tip: Always follow rules for quality checks. Keep things clean. Heating and cooling must match the maker’s guide. Wires should not be damaged. Solder must cover the tinned area. Use AOI and AXI for checks. Fix or throw away coils that do not meet standards.
