I.C.T Reflow Soldering Oven Factory: Specs and Applications for Every Scale
As I.C.T, we proudly manufacture a comprehensive range of SMD Soldering Oven solutions as a trusted Reflow Soldering Oven Factory, delivering equipment tailored to diverse SMT production scales—from compact prototypes to high-volume lines. Our lineup includes the T series for small setups, L series for cost-effective efficiency, Lyra series for advanced performance, and LV series for vacuum precision, ensuring reliable soldering for every application.
1. Compact T Series for Small-Scale SMT Needs
1.1. T4 Model Specifications
We design the T4 as our entry-level extreme mini reflow oven with 4 temperature zones. It features a combined rail and mesh belt system, where the rail width reaches 300mm. This model suits limited space environments, offering precise control for low-volume runs. Heating elements distribute heat evenly across zones, supporting preheating, soaking, reflow, and cooling stages. Power consumption stays efficient, typically under 10kW during operation, making it ideal for workshops or R&D labs. The conveyor speed adjusts from 0 to 1000mm/min, allowing fine-tuning based on PCB requirements.
We equip the T4 with a user-friendly touchscreen interface for profile setting. Temperature accuracy holds within ±1°C, ensuring consistent results. The oven body uses high-quality insulation to minimize heat loss, and exhaust systems manage fumes effectively. For maintenance, we make components accessible, reducing downtime. This model handles PCB widths up to 300mm, perfect for small boards in aerospace or medical devices.
1.2. T6 Model Specifications
Building on the T4, we offer the T6 with 6 temperature zones for enhanced thermal profiling flexibility. It retains the rail and mesh belt combo with 300mm rail width. Additional zones allow better management of complex solder pastes, especially those needing longer soak times. Peak power draws around 12kW, still energy-efficient for its class.
We integrate independent zone controls in the T6, each with upper and lower heaters. Conveyor options include adjustable speeds and dual-direction capabilities. The cooling zone uses forced air to rapidly drop temperatures, preventing thermal stress on components. Software supports data logging for process validation. We build the frame from durable stainless steel, resistant to corrosion in humid environments.
1.3. Ideal Applications in Low-Volume Production
We recommend the T series for scenarios where production volumes stay below 1000 boards per day. Prototyping houses benefit from quick setup times, often under 30 minutes to reach stable profiles. Universities and startups use these for testing new designs without investing in larger equipment. The compact footprint, around 2m in length, fits benchtop or small cleanroom spaces.
In low-volume settings, we see the T series excelling with lead-free solders requiring precise ramps. It handles fine-pitch components down to 0.4mm without bridging issues when profiles optimize correctly. Energy costs remain low, appealing to budget-conscious operations. We provide optional nitrogen inlet for oxidation-sensitive applications, though standard air mode suffices for most.
1.4. Customer Case: Aerospace Micro Motor Control Boards
We supplied a T4 to an aerospace client producing micro motor control boards. Their requirements demanded extreme reliability with low yield but zero tolerance for defects. Previously, they used manual dotting of solder, inspecting under 200x magnification for full encapsulation of component pins, no cold joints, or virtual soldering.
After switching to our T4, we helped optimize a profile with slow ramp rates to ensure complete melt. The 4 zones allowed gentle preheating to avoid popcorn effects on moisture-sensitive parts. Post-reflow inspections showed 100% pin coverage and no voids. Production time dropped from hours per board to minutes, maintaining quality. Our engineer trained their team on profile creation, resulting in certification-ready boards for aviation standards.
2. Cost-Effective L Series for Mid-Range Efficiency
2.1. L8 Flagship Model Details
We position the L8 as our terminal-priority high-sex价比 reflow oven with 8 temperature zones. It combines rail and mesh belt, offering 400mm rail width and 500mm mesh width. This model targets mid-volume lines needing reliability without premium costs. Total length spans about 4.5m, with power around 38kW at peak.
We include independent PID controls for each zone, ensuring ±1°C uniformity. The conveyor system supports edge rails or mesh, adjustable for PCB sizes up to 400mm. Cooling uses multiple fans for efficient heat dissipation. Interface features Windows-based software for recipe storage and real-time monitoring. We add UPS backup for power stability in fluctuating grids.
2.2. L Series with CBS Enhancements
We enhance the L series with CBS, or Center Board Support, preventing warpage on larger PCBs. This adjustable central rail supports boards in the middle, distributing weight evenly during heating. It proves crucial for double-sided assemblies or thin substrates prone to bending.
CBS integrates seamlessly without reducing throughput. We calibrate it for various board thicknesses, from 0.4mm to 5mm. In operation, it reduces defects like tombstoning by maintaining flatness. Maintenance involves simple bar adjustments, no tools needed. This feature sets our L series apart in cost segments, rivaling higher-end stability.
2.3. Balancing Performance and Budget
We engineer the L series to deliver 80% of high-end performance at 50% cost. Zones provide sufficient flexibility for most lead-free profiles, with ramp rates up to 3°C/s. Throughput reaches 500-1000 boards per hour, suiting growing factories. Energy efficiency includes insulation upgrades, cutting utility bills by 15% versus competitors.
We focus on durability with Japanese bearings and European motors, extending lifespan to 10+ years. Spare parts availability ensures quick repairs. For expansions, L models scale easily by adding upstream printers or downstream AOI. This balance makes L series a smart upgrade from manual or mini ovens.
2.4. Customer Case: Saudi Arabia LED Home Lighting Factory
We partnered with a Saudi client manufacturing home LED lighting. They needed a full automatic SMT line with 13 machines, totaling 29m length, but space limited to 21m x 5m. We redesigned into a U-shape, fitting within 16m x 2.7m.
The L8 served as the core reflow, handling high-volume LED boards. Installation took 2 days, debugging another 2, followed by 6 days of training. Our engineer Roka covered operation, maintenance, and troubleshooting. Post-delivery, yield hit 99.5%, with CBS preventing warpage on flexible LED strips. The compact layout maximized floor use, boosting output without relocation.
