Koh Young Zenith 3D AOI Machine

Product Overview
Optical inspection sits downstream in an SMT assembly line, looking at boards once components are on them. The unit carried here is presented under the product name Koh Young Zenith 3D AOI Machine, with brand Koh Young and model Zenith, and the application field places it in SMT PCB assembly production lines. Ten attributes make up the whole record: the condition field reads New, the physical data gives a PCB size of 330x330mm, a minimum PCB figure of 50 x 50 mm (1.97 x 1.97 in), an overall dimension of 820x1265x1627mm and a weight of 550 kg, and delivery is listed as DHL, UPS, FedEx, TNT and EMS. How those two board figures relate to one another is not spelled out on the page, and we do not relabel them — ask, and the reading is confirmed.

Footprint and Floor Planning
- PCB size field: 330x330mm, reproduced as printed.
- Minimum PCB field: 50 x 50 mm (1.97 x 1.97 in), with the imperial figure the page also carries.
- Machine dimension: 820x1265x1627mm.
- Machine weight: 550 kg.
- Neither board figure is called the maximum anywhere on the page: one is labelled PCB size and the other Min PCB, and that wording is kept as it stands.
Key Features
1. Product Name, Brand and Model — Koh Young Zenith 3D AOI Machine, Koh Young, Zenith, as the attributes carry them.

Before You Order
- The technical detail an inspection engineer would want is absent from the attributes. Nothing is filled in for it here from general expectation — give us the duty you need covered and the answers are drawn from the machine on offer.
- The board figures are printed as one PCB size and one minimum, with no maximum stated and no relationship explained between them. Tell us your product size and the figure that governs your upper limit is confirmed.
- Dimension and weight are given above; the entry route and floor loading for your site are worked through with you before anything is agreed.
- A guarantee term and a packing description both sit outside the attributes here, so neither is quoted. Ask, and both are supplied alongside the offer.




Why Choose WEN ZHAN Technology
Inspection earns its place only when it finds what a line actually produces. WEN ZHAN Technology has supplied SMT equipment and complete lines for over two decades, so the items this page leaves open are answered from machine records instead of a sales pitch: describe the products you assemble and the duty you want the inspection to perform, and the unit is measured against that duty, its state and its paperwork are put in front of you, and the commercial terms follow on the delivery route you select.




FAQ
Q1: What work does this machine do on a line?
A: Optical inspection on an SMT PCB assembly production line — the application field as printed on the page.
Q2: Which board sizes are covered?
A: The attributes give a PCB size of 330x330mm and a minimum PCB of 50 x 50 mm (1.97 x 1.97 in), in those terms.
Q3: Which of the two board figures is the upper limit?
A: Neither is labelled a maximum on this page. Give us your product size and the reading that governs your limit is confirmed.
Q4: How much floor space and weight should be planned for?
A: Dimension is listed as 820x1265x1627mm and weight as 550 kg; check both against your bay and your access route.
Q5: What technical detail is published for this machine?
A: The attributes carry no technical figures beyond the fields listed, and none is filled in on this page. Give us the duty to be covered and the machine's own data is obtained for you.
Q6: What state is the unit in?
A: The condition field reads New; the state and history of the particular unit are confirmed with your enquiry.
Q7: Which carriers are listed for delivery?
A: DHL, UPS, FedEx, TNT and EMS, as the delivery attribute states.
Q8: What guarantee terms apply?
A: None is published in the attributes, so no term is stated on this page. Ask, and the cover on your unit is put in writing.
Q9: How does this machine differ from an SPI unit?
A: The two are built for different check points on a line, and our SPI listing covers the other one. Tell us where your check point sits and we will point you to the right machine.
