Short answer: The JT-MFO is a tunnel solder reflow oven from JT Automation for SMT PCB soldering. It runs 8 top and 8 bottom heating zones with 3 top and 3 bottom cooling zones over a 3,110 mm heated length, and it accepts boards up to 400 mm wide. An optional nitrogen model (MFO-800-N) is available, and the page lists the machine at US$50,000 with an MOQ of 1 set. Two fields on that page disagree — see "Two values to confirm" below.
The JT-MFO is a tunnel reflow oven: boards enter at one end, travel through heated zones and a cooling section on a conveyor, and exit with the solder joint formed. It is the workstation that follows placement in a standard SMT line.
The page carries the product under machine type "Solder Reflow Oven", brand JT, with the specification table attributed to brand JT Automation and model MFO-800 / MFO-800-N, where the N suffix denotes the nitrogen model. Outer dimensions are 5,520 × 1,430 × 1,530 mm (L×W×H) — a long footprint that shapes the line layout.

The page is internally inconsistent in two places, and both affect what you receive:
Weight. The attribute area states 2,500 KG; the specification table gives 2,400 KG (Air) / 2,500 KG (N2). The two agree only if the quoted machine is the nitrogen version — which matters for floor loading, lifting and freight.
Model. The attribute area states JT-MFO; the specification table gives MFO-800 / MFO-800-N. Treat JT-MFO as the series reference and MFO-800 / MFO-800-N as the model designations.
Neither is a machine defect; both are documentation issues. Have the supplier name the exact model and its net weight in writing on the quotation.
Sixteen heating zones plus six cooling zones is a profiling decision before it is a specification. A tunnel oven holds each zone at its own setpoint, so more zones means the ramp, soak and reflow phases can be shaped more finely. On a 3,110 mm heated length, that zone count is what lets one machine be profiled for several board types instead of being locked to one product.
Control is by PID closed-loop regulation, which adjusts heating continuously against the measured zone temperature, and heat transfer is by dual-channel forced hot air convection. The published range is room temperature to 300°C, with a warm-up time of around 25 minutes.
Two process numbers shape the facility plan. Exhaust: 2 outlets at 10 m³/min each need matching ducting. Power: a 30 32KW startup maximum against 9 10KW stable running means the supply must be sized for startup, not running. Supply is AC 380V 3-phase 5-wire 50/60Hz, with a custom 220V 3-phase option.
Nitrogen inerting is an option, and it is what separates the N2 type from the Air type. Reducing oxygen in the heated zones limits oxidation of paste and pad during reflow, which is why buyers specify it for oxidation-sensitive work: fine-pitch assemblies, tarnish-prone finishes and tightly controlled wetting behaviour.
Practically, the N2 type is listed at 2,500 KG against 2,400 KG for the Air type. Inerting also changes the facility requirement — nitrogen supply and consumption are not in the published spec table, so ask what the quoted N2 configuration needs. If inerting is not required, the Air type is lighter and simpler.
The page lists these application areas:
Automotive electronics: ECU, BMS, new energy vehicle control boards.
Medical precision circuit boards.
Consumer electronics: laptop, mobile and smart-home mainboards.
Industrial control and power supply PCBs.
LED lighting and communication server boards.
They share one trait: boards carrying fine-pitch components and larger devices on the same panel — where the 16 heating zones let the profile be shaped for the board rather than compromised for the mix.
In the line, the JT-MFO sits at reflow: boards arrive from placement, pass through the heated and cooling zones, and continue to AOI and handling. Because Wenzhan supplies the surrounding equipment, including complete SMT lines, the conveyor and handling equipment upstream can be matched to the oven's 400 mm maximum board width and infeed height.
Board width: published maximum 400 mm — measure your widest panel with edge clearance.
Profile requirement: count the distinct thermal profiles your mix needs; the 16 heating zones provide the room to build them.
Air or N2: decide whether inerting is required, then quote the matching model.
Electrical supply: plan for the 30~32KW startup on AC 380V 3-phase 5-wire, or confirm the custom 220V 3-phase option.
Exhaust and floor: duct for 2 outlets at 10 m³/min each; allow a 5,520 × 1,430 × 1,530 mm footprint at 2,400–2,500 KG.
Ask for the exact model designation (MFO-800 or MFO-800-N), the net weight that applies to it, whether inerting is included, the voltage configuration, and the packing, delivery and warranty terms. The page does not publish warranty, packing or delivery terms for this unit — those come from the quotation.
At handover, confirm each zone reaches and holds setpoint and that your board runs the profile you intended, then inspect the conveyor, mesh belt, blowers and exhaust path. Heating elements, thermocouples and conveyor components are the wear items to plan for; Wenzhan stocks SMT spare parts alongside the machines.
The page lists the JT-MFO at US$50,000 with an MOQ of 1 set. Treat that as the listed price rather than a final quotation: what applies to your order depends on the configuration — Air or N2, the 220V 3-phase customization, accessories and the logistics plan — and on when the quotation is issued. The page states no Incoterms, freight cost, duties or lead time, and none should be assumed from the listing.
On quality process, the supplier states that it runs a pre-production sample before mass production and a final inspection before shipment. Use that as the basis for agreeing your own inspection and acceptance step in the contract.
What is the JT-MFO reflow oven? A tunnel solder reflow oven from JT Automation for SMT PCB soldering, available as the Air type or the nitrogen MFO-800-N type, with a 400 mm maximum PCB width.
How many heating and cooling zones does it have? 8 top plus 8 bottom heating zones and 3 top plus 3 bottom cooling zones, over a 3,110 mm total heated length.
Can it run with nitrogen inerting? Yes — inerting is listed as an option and corresponds to the MFO-800-N model. The N2 type is listed at 2,500 KG against 2,400 KG for the Air type.
What PCB size does it handle? The published maximum PCB width is 400 mm. Confirm the board length your product needs with the supplier.
What power supply and consumption does it need? AC 380V 3-phase 5-wire 50/60Hz, with a custom 220V 3-phase option. Consumption is listed at 30 32KW maximum at startup and 9 10KW in stable running.
How much does it cost, and what is the minimum order? The page lists US$50,000 with an MOQ of 1 set. The final price depends on the configuration and the quotation period.
Why do the model and weight differ on the page? The attribute area shows Model JT-MFO and Weight 2,500 KG; the specification table shows MFO-800 / MFO-800-N and 2,400 KG (Air) / 2,500 KG (N2). Ask the supplier to state the exact model and net weight on your quotation.
Send your widest panel, the number of distinct thermal profiles in your mix, and whether inerting is required, then ask for a quotation naming the exact model, net weight, voltage configuration, packing and delivery terms. Compare it with the other JT reflow ovens in the range, or browse the wider reflow oven category if a different heated length or board width suits your line better.
