COMPONENT
Phosphorus-diffusion quartz boat
Futong Quartz (Zhejiang) ↗A quartz wafer boat built for phosphorus diffusion in solar-cell furnaces. Futong names it by length; slot layout, loading and thermal limits are set on the drawing for your order.
Single component: Futong calls it the S 1.1-metre phosphorus-diffusion boat. It carries no separate model code, and the slot schedule comes with the quotation drawing.
General illustration of cell production equipment, not a photograph of this model. Ask the manufacturer for current photographs and layout drawings of the configuration offered.
START WITH YOUR PRODUCTION TASK
Start from your furnace drawing and wafer arrangement. Futong's boat is chosen by its interfaces, material and inspection terms, which the photo and length label cannot settle on their own.
SOURCE-LINKED DATA
Published specifications
Values below are published by the manufacturer, each with the date its source was checked. Ask for the figures that apply to your configuration and material in the quotation.
The manufacturer has not published a complete specification table for this entry. Request the delivered material specification, drawing where applicable and lot acceptance requirements.
01 · Manufacturer information
Futong's 1.1-metre boat and its catalogue neighbours
Futong lists the 1.1-metre phosphorus-diffusion boat in its photovoltaic range. Nearby entries include smaller boats, vertical-insertion and horizontal-insertion designs, and short and long carriers. Each of these is its own enquiry, so a carrier only comes with this boat if your quotation says so, and furnace fit depends on your drawing.
The boat page carries specification and description headings, but the readable content has no slot schedule, quartz grade, wafer capacity or thermal range. Treat the length in the name as a way to identify the product, and order from a controlled, dimensioned drawing.

Settle these interfaces before asking Futong for a price
| Drawing topic | Why it matters for the quote |
|---|---|
| Support and datum geometry | The boat has to seat on your furnace and carrier interfaces. |
| Slot pitch and wafer arrangement | Loading orientation and real wafer geometry drive the boat drawing. |
| Handling and robot access | Say how the boat is loaded, held in place and moved. |
| Revision and interchangeability | Two boats of similar length may still differ, so compare drawings before swapping. |

Records to ask Futong for with the boat
Material identification
Ask which quartz grade Futong quotes, with its traceability records and the acceptance limits that go with that grade. Purity and temperature ratings should be stated for this boat in writing.
Dimensional and condition checks
Agree the drawing revision, the datums to measure, slot geometry and the finished condition to inspect. Futong runs cold-working, grinding, annealing and QC facilities, and the inspection tolerances for this boat belong in the order.
Cleaning, packing and receipt
Work out the process-sensitive cleaning and handling rules with whoever owns the receiving furnace. Ask Futong how the cleaned boat is protected in transit and which checks you run on arrival before releasing it for installation.

Qualifying the boat in your own furnace
Who signs off the process
Your process owner decides which thermal exposure, handling checks and contamination measurements qualify the boat. A boat built to drawing is a starting point; diffusion uniformity and cell electrical results are proven in your own line. Diffusion sits early in cell production, right after texturing, so contamination from the boat travels through every later step.
Service life
Futong publishes no lifetime for this boat. Ask what condition monitoring and rejection criteria it recommends for your cycle, and agree a service interval or batch count only on data Futong can show.

What a complete Futong boat quotation should cover
Receiving machine
The furnace-side drawing and its revision, beyond the furnace brand name.
Required loading
Wafer dimensions, loading orientation and the agreed slot schedule. Share how your automated loader picks wafers, since wafer handling clearances follow the slot design.
Inspection deliverables
Material identification, dimensional checks, and cleaning and packing records.
Qualification ownership
Who approves installation, and the acceptance conditions for your process.

Questions buyers ask about this boat
How many wafers does it hold?
The detail page gives no count. Ask Futong for the slot schedule and loading drawing.
Is this a complete diffusion furnace?
No. It is a quartz process part; the furnace and its process controls are a separate equipment purchase.
Can I use a carrier length as the boat specification?
No. Futong sells carriers and boats separately, so confirm each interface on its own drawing.
