The I.C.T-SS430 offline selective soldering machine is made for factories that need flexible soldering without placing the machine inside a full online conveyor line. Operators load the PCB or fixture into the machine, then the spray and soldering platform moves by program. This design is useful for small-batch production, repair work, NPI samples, and PCBA products with mixed SMT and DIP parts.

All main process settings can be saved in the PC system. These include moving path, flux type, solder type, solder temperature, nitrogen temperature, and wave height. When the same product is produced again, the operator can call the saved program and reduce repeated setup work.

The off-line selective wave soldering machine process includes flux spraying, preheating, and selective soldering. First, the German jet valve sprays flux only on the needed soldering area. The standard spray nozzle size is 130 μm, with 180 μm and 210 μm as options. The spray range is 3–8 mm, and the spray pressure is 0.05–0.1 MPa.

After fluxing, the PCB moves through IR bottom preheating. This helps activate flux and reduce temperature shock before soldering. Then the solder nozzle moves to each programmed point. 

Flux control is one of the key parts of selective soldering. The I.C.T-SS430 uses a pressure tank to keep flux supply stable. A high-precision pressure flow meter helps control flux flow, and corrosion-resistant material is used in the flux path. This helps reduce unstable spraying during daily production.

The preheating system uses IR heating. The preheating area is 300 x 350 mm for SS430. The temperature can be set from room temperature to 250°C, and the warm-up time is about 15 minutes when set to 150°C. Good preheating helps improve hole filling, reduce solder balls, and make the automatic selective soldering machine process easier to control.

The soldering system uses an electromagnetic pump to keep the solder wave stable. The solder pot is made of titanium alloy and has a 12 kg solder capacity. The nozzle inner diameter supports 2.5–30 mm, and special nozzle sizes can be customized for different pad layouts and component spacing.

The I.C.T-SS430 offline selective soldering machine also has automatic nozzle cleaning. The cleaning frequency can be adjusted based on production needs. It also uses laser wave height detection with a German SICK non-contact sensor. This helps check the wave height without touching the solder, so the machine can keep a more stable soldering result during long production runs.

The operating system supports guided programming, CCD fast programming, picture programming, coordinate correction, and coordinate verification. Operators can view real-time process data on the interface and switch to CCD soldering monitoring when needed. The system supports Chinese, English, Japanese, Russian, and other languages.

For factories using an automatic selective soldering machine, easy programming matters a lot. Operators often need to create new programs for different PCBA models. SS430 helps reduce programming difficulty by using image-based support and saved process data. This is useful for factories that handle many product types but do not need a full inline selective soldering line.

Factory And Solution Ability

I.C.T is a factory and full-line solution provider for SMT, DIP, and PCBA production. We support customers from early line planning to final production. Our work includes machine selection, layout design, utility planning, fixture advice, process setup, operator training, and long-term technical support.

For customers choosing an offline selective soldering machine, I.C.T does not only sell the machine. We help check whether the PCB is suitable for offline production, inline production, wave soldering, or manual soldering replacement. If the customer is building a full factory, we can also plan SMT printing, placement, reflow, AOI, DIP insertion, selective soldering, coating, handling, and testing equipment together.

Machine Testing Before Delivery

Before shipment, I.C.T checks the machine structure, wiring, software, motion system, flux system, preheating system, soldering system, CCD function, laser wave height detection, and nozzle cleaning function. For SS430, the team also checks offline loading, fixture holding, solder pot heating, spray flow, and program saving.

This test is not just a simple power-on check. Our engineers confirm whether the machine can follow the real production process. If the customer provides PCB drawings, photos, or samples, I.C.T can review the soldering path, nozzle choice, flux area, and preheating need before delivery. This helps reduce setup time when the machine arrives.

Customer Case Support

I.C.T selective soldering machines are used for automotive electronics, industrial control boards, power boards, communication products, LED boards, and other mixed PCBA products. Many of these boards have SMT components and through-hole parts on the same board, so full wave soldering may not be the best choice.

In real projects, customers often need support with flux amount, preheating temperature, solder temperature, nozzle size, fixture design, and soldering path. I.C.T engineers help customers review these details during setup. For new products or low-volume production, an offline selective soldering machine can be a practical choice because it gives more flexibility and needs less line space.

After-Sales Service

I.C.T provides installation guidance, operation training, programming training, process setup, maintenance training, and spare parts support. Engineers can support customers onsite or by remote video, based on project needs. Training covers program creation, flux setting, preheating adjustment, solder wave height, nozzle cleaning, daily maintenance, and defect checking.

For an automatic selective soldering machine, the process is just as important as the hardware. A wrong nozzle, weak preheating, or poor fixture can cause bridges, poor hole filling, or unstable soldering. I.C.T helps customers check these points step by step, so the production team can move from trial run to stable output faster.

Certificates And Quality

I.C.T equipment follows international production and safety requirements. For full-line projects, I.C.T can support CE, ISO9001, and ISO14001 related project needs. These documents help customers with import, factory audits, project acceptance, and internal quality records.

Quality control covers more than machine assembly. I.C.T checks key electrical parts, motion parts, spray control, heating control, soldering stability, safety protection, and software functions before shipment. For overseas projects, we can also prepare manuals, packing photos, test photos, training documents, and maintenance guides based on the customer’s project needs.

Customer Feedback

Customers often value I.C.T because we help solve real production problems, not just send equipment. In selective soldering projects, the common issues are solder bridges, poor hole filling, nozzle blocking, unstable flux spraying, wrong fixture design, and weak preheating. These are not solved by machine price alone.

Many customers give good feedback after installation because I.C.T engineers help them adjust the process around the actual PCB. For new factories, this is especially important. The team needs to learn how to set parameters, check soldering quality, and maintain the machine. I.C.T helps customers build this ability, so the machine becomes a working production tool, not just a nice box on the floor.
