1. What accuracy is specified, and how is it verified?
Ask for the attachment accuracy as a number with a sign, not a marketing phrase. On our TGV Alignment Packaging Machine Solution page the conformity accuracy is stated as ±0.03 mm for a glass panel of 191.59 × 172.52 mm bonded with four PI films of 94.79 × 83.26 mm. Then ask how that number is demonstrated: with which measurement tool, on how many consecutive cycles, and at which point in the shift. A figure measured once on a warm machine at the factory and a figure logged across a production run are two different commitments, and the difference will decide whether the station passes your incoming inspection.
A practical follow-up: request the alignment method in the same detail. Camera photography for positioning with an X, Y and θ adjustment platform, together with vacuum plate bonding, is what holds the registration steady; a supplier who cannot describe the mechanism behind the tolerance is quoting an aspiration rather than a process.
2. Who fixes alignment bubbles, and how fast?
Bubbles at the alignment step are the failure mode that costs the most, because the glass and the film are usually already committed to the bond. Our machine is built around an adsorption platform sequence — pressing, pre-bonding, vacuum pumping and then bonding — so that alignment takes place once the negative pressure reaches the set value, which is the design point that keeps bubbles out of the process. Ask a supplier to walk you through their own sequence in the same order, and ask what they change first when bubbles appear on your line.
Then put a time on it. Confirm in writing who responds when the station stops producing good parts: an engineer on site, a remote session with the vision system, or a parts shipment. For a single-station packaging cell, an overnight wait is a full shift of lost output, and it is cheaper to agree the response terms before the purchase order than to negotiate them during a breakdown.
3. How much of the support burden falls on your engineers?
Ask what an operator can do alone and what always needs a specialist. On this machine the touchscreen human-machine interface and the selectable program recipes are the two features that shift work back to your own team: recipes can be packaged one-to-one against different product processes, so a changeover does not require a vendor visit, and machine adjustment stays fast. Ask any supplier how a new product recipe is created, who is allowed to create it, and how a wrong recipe is rolled back.
Ask the same about the vision system. The CCD used here carries a measurement function, and the measurement data can generate local marks or be networked for collection. If your quality engineer can read those numbers directly, a drift in registration shows up as data on a dashboard instead of as a scrap pile at the end of a run.
4. What is included in the commissioning package?
Get the scope in writing: installation, alignment to your glass and film dimensions, training for named operators, and a defined acceptance run with your own materials. Note the process constraints early so nobody is surprised on site — the machine described here takes manual feeding of both the glass panel and the PI film, with camera positioning handling the registration, and it produces roughly 8–10 pieces per hour given that each product needs four bond cycles. Manual feeding is normal for this class of precision cell, but it changes your staffing plan, and it is a fact you want settled during quotation rather than at commissioning.
Room planning belongs in the same conversation. The external dimensions, including the vacuum pump and the FFU height, are L2260 × W1700 × H2300 mm, and the cell carries an FFU ion cleaning module plus a safety light curtain. Ask your supplier to confirm the utility and footprint requirements — power, compressed-air-free areas, cleanroom class, pump exhaust — before the machine is scheduled into your floor layout.
5. What happens to your data?
Ask whether the equipment stores process and measurement data, and whether it connects to your MES. This machine ships with an industrial computer and data connection to MES with data storage, which is what lets you trace a bonded lot back to the exact alignment condition it was made in. Ask who owns that data, in what format it leaves the machine, and whether the interface is documented for your IT team rather than locked inside the vendor's tooling.
6. What does the spare-parts and service agreement actually cover?
Ask which consumables and wear items you should hold on site, what the lead time is for the rest, and how long the vendor guarantees parts availability. Vacuum plates, adsorption platforms, cameras and the ion cleaning module all have different replacement rhythms; a supplier who can name them with lead times is running a support organisation, while one who answers "contact us when it fails" is handing the risk to you. Also ask whether remote diagnostics on the industrial computer are available, since most alignment complaints can be triaged from the logged data long before a service engineer arrives.
7. Can the machine be adapted to the next product, not only this one?
Ask what a product change costs in engineering time and in hardware. Multiple program recipes cover process variation, while a genuine change in panel format touches the fixtures, the adsorption platform and the alignment program. Our engineering-services pages list engineering services and non-standard automation equipment work, because in this segment customers routinely need the cell re-specified rather than simply re-bought; ask every supplier how they price and staff that second phase.
A short checklist for your supplier call
- Attachment accuracy as a signed figure, plus how and when it is measured
- The bond sequence, and the first response when alignment bubbles appear
- Which tasks your operators can perform without a vendor engineer
- Commissioning scope, training, and an acceptance run on your materials
- Footprint, utilities and cleanroom requirements stated before layout
- MES data connection, data ownership and export format
- Consumables list, lead times and remote diagnostics
Bring your glass and film dimensions to the first conversation, not the last. If you want the parameter table for the machine described above, or need to size a cell around a different panel format, the contact page reaches our engineering team directly, and semiconductor process equipment listings show the adjacent bonding and laminating stations that sit around this one in a line.
