Short answer: The HY-250LD is the smallest of four magazine PCB loader and unloader models — HY-250LD, HY-330LD, HY-390LD and HY-460LD — which share nine operating parameters and differ in board size, magazine rack and footprint. Boards move by pusher, not by hand: a loader pushes them out of the magazine on to the downstream conveyor, an unloader pushes incoming boards in. HY-250LD takes boards from 50×50 to 350×250 mm at 0.4 mm minimum thickness. Its Model Number field reads "PCB Loader" rather than a model code, so the model is confirmed on the order and quotation.
A full magazine of bare boards goes in at the head of the line and a magazine of finished boards comes off the end, with no operator lifting each panel by hand.
At the loading end the unit pushes each board out of the magazine on to the conveyor of the machine downstream. At the unloading end a board arriving on its own conveyor is pushed into the magazine, which indexes to the next slot.
The same platform serves either end because transfer direction is selectable, left to right or right to left, so a unit does not have to be rebuilt to change ends. Tell the supplier which end it will stand at.
The page records the product name as "SMT PCB Loader Machine", type "SMT Machine", brand "ODM", package "Wooden Case" and quality as "Top". The Model Number field reads "PCB Loader" — a generic label, not a model designation: the page covers four models and its title is anchored on the smallest, HY-250LD. State the model you want, or state your board and magazine dimensions and let the matching model be confirmed.
The four models are supplied as listed; a build that departs from them is handled as an ODM requirement, with the specification reviewed before a quotation is put together.

Three carry an "or specify" escape: feed time, magazine change-over time and indexing pitch. Read those as default behaviour, not a fixed limit — if your process needs a different pitch or cycle, raise it before the order, not afterwards.

The model follows the board, and all four accept boards as small as 50×50 mm and as thin as 0.4 mm.
Selection runs on two dimensions. The first is the board: measure your largest panel with carrier and edge clearance, and pick the smallest model that clears it. The second is the magazine: a model only works if your existing magazines fit its rack. Footprint and weight track the model too — check them at the line end, where space and floor loading are tighter than they look.
Boards are moved by a pusher rather than by hand: at the loading end it takes a board out of the magazine and sets it on to the downstream conveyor, and at the unloading end it sets an incoming board into the magazine. The safety design targets the failure mode that matters on thin panels — a board breaking as it is pushed.
The magazine indexes to the next slot after every board, which is what keeps the cycle running without attention. Indexing pitch is selectable between 1 and 4 at 10 mm pitch, so slot spacing can match the board thickness.
The control set carries automatic counting and a fault alarm, so a full magazine or a transfer fault is signalled at the machine rather than found further down the line. Supply is single phase at 300VA max, with 4-6 bar air at up to 10 ltr/min.
Two numbers decide whether a unit integrates cleanly: the 900 ± 20 mm PCB delivery height, which must line up with the adjacent conveyor, and direction, set L-R or R-L.
Plan the rhythm around the published cycle figures — feed time approximately 6 seconds, magazine change-over approximately 20 seconds. Those two tell you how many magazines to keep in rotation, because a change-over during running is invisible and one that stops the line is not. Wenzhan also supplies the equipment these units hand off to, including PCB conveyors and complete SMT lines, so transfer height can be matched across the line.
Board envelope: largest panel with carrier and edge clearance inside the model's PCB size range.
Magazine fit: your magazine dimensions against the model's rack size — this rules models in or out faster than the board size does.
Line end and direction: state which end the unit stands at and whether it feeds L-R or R-L.
Transfer height: 900 ± 20 mm against the adjacent conveyor.
Utilities: 100/230 VAC single phase at 300VA max, and 4-6 bar air at up to 10 ltr/min.
Footprint and floor loading: 1,100×780×1,200 mm to 1,600×1120×1200 mm, 140 kg to 250 kg.
Condition: original or copy — say which one you need, in writing.
Check the pusher travel and board support, confirm the magazine indexes once per board at the pitch ordered, test the counter and fault alarm including a full magazine, and confirm your magazines load without binding. Wear parts for the line — belts, cylinders, nozzles — come from the same supplier under SMT spare parts.
The unit ships in a wooden case from Shenzhen, on the carrier named on the order — UPS, DHL, FedEx or as your order requires. Payment is listed as L/C, T/T, D/P, Western Union, Paypal, Money Gram and others; warranty 1 year.
Two fields need care. Shipment is recorded as "In three days" — page wording, not a general promise; your schedule comes with the quotation. Condition is "original/copy", meaning original and copy builds are both offered; name the one your order needs.
The page does not publish a price, an Incoterm, a freight cost or a duty estimate, and none should be inferred from the listing.
How many models are there, and how do I pick one? Four. HY-250LD takes boards up to 350×250 mm, HY-330LD to 455×330 mm, HY-390LD to 530×390 mm and HY-460LD to 530×460 mm. Pick by board size, then confirm your magazines fit that model's rack.
Does one unit both load and unload? The loader pushes boards on to the line and the unloader pushes boards into a magazine. Tell the supplier which end of the line the unit will stand at.
Which direction does it feed? Either — direction is set L-R or R-L, and the same unit can be placed at either end of a line.
What supply and air does it need? Single phase at 300VA maximum, and 4-6 bar air at up to 10 ltr/min.
What board thickness and smallest board will it take? 0.4 mm minimum thickness and 50×50 mm minimum board size, on all four models.
How does it ship, and how fast? In a wooden case from Shenzhen. The page records shipment as "In three days"; the schedule for a specific order comes with the quotation.
Why does the Model Number field say "PCB Loader"? Because it is a generic label, not a model code. The page covers four models and is titled after the smallest, HY-250LD — confirm the exact model on the order and quotation.
Send your board size, your magazine rack size, the line end the unit will stand at, and the supply available at that point, and the matching model is confirmed with the price. Compare the range in the PCB loaders category if a different board envelope or rack size suits your line better.
