When a glass-through-via alignment and packaging project reaches the quotation stage, most buyers receive several machine proposals that all say the same thing: high precision, CCD alignment, high yield. The differences are usually hidden in what is not written. Before signing a purchase order, ask the supplier for a defined set of documents and test records, then check them against the process you actually run. This is the list we suggest buyers request for a TGV alignment packaging machine project, and why each item matters.
1. A process input sheet signed by your own team
The machine specification should start from your inputs, not from a catalogue. Request a written sheet that records glass thickness and size, via pitch and diameter, the film or glass being aligned to it, allowable alignment tolerance, target throughput, and the cleanroom class where the equipment will be installed. A supplier who will not document these inputs is quoting a standard build, not your process. Where the work involves glass plate and PI-film soft alignment, the recipe flexibility matters: the TGV alignment packaging machine solution listed by Shenzhen PowerDe Automation Precision Equipment is described as a high-precision TGV process with selectable recipes intended to reduce alignment bubbles, which is exactly the kind of configurable behaviour you want stated in writing.
2. An alignment and bonding definition of terms
Ask for the measurement definition behind every accuracy number: reference marks used, whether the figure is per-axis or total shift, ambient temperature, and the substrate size the number was obtained on. Then request the same definition for defects. "Low bubble rate" is not a deliverable; a defect classification sheet that separates alignment bubbles, entrapped particles and delamination is. Insist that the vendor's defect vocabulary matches your incoming inspection sheet, otherwise acceptance testing becomes an argument about words.
3. A written acceptance test protocol with your samples
The single most valuable deliverable is an acceptance protocol agreed before the machine ships. It should state the sample lot you supply, the number of cycles, the sampling plan for alignment measurement, the pass criteria for each criterion, and what happens when one criterion fails. Ask specifically whether the trial runs use your own glass and film or the vendor's demonstration material. A machine qualified on the supplier's coupon is not qualified on your lot.
4. Recipe and changeover documentation
Request the recipe structure: which parameters are operator-accessible, which are engineering-level, and how a new product is introduced. For multi-product lines, ask for the documented changeover time between two of your real product variants, plus the recovery steps after an abnormal stop. Ask also how recipes are backed up and restored after a software update.
5. Consumables, utilities and spare-parts list
Ask for the full utility connection sheet (power, compressed air, exhaust, gases if any), the consumable list with expected life, and a recommended spare-parts package with lead times and part numbers. Machines that look competitive at purchase price often cost more over five years because consumables and long-lead spares were never quoted. Confirm which items are stocked locally and which ship from the factory.
6. Integration and installation plan
Request a drawing package with footprint, service access, loading path and door sizes, plus a written installation and commissioning sequence with who provides what. If the equipment must work alongside lamination, bonding or debubbling steps already on your floor, say so in the scope conversation. PowerDe's equipment range includes semiconductor process equipment such as vacuum laminating, bonding and high-pressure debubbling machines, so buyers combining several steps can ask one supplier to state the interfaces between them rather than assuming compatibility.
7. Training, service response and escalation
Ask for the training syllabus, who it is written for (operator, process engineer, maintenance), how long it lasts, and whether refresher training is available after warranty. Get the service response commitment in writing: remote support hours, on-site response window, spare-parts dispatch, and the escalation contact after the first line stops. A named engineer and a defined escalation path are worth more than a generic service promise.
8. Risk and change-control clause list
Finally, ask how changes are handled. Who can change a specification after order confirmation, what re-qualification follows a design change, and how schedule impact is decided. Written change control protects both sides and is a good indicator of how the project will be managed.
A simple way to use this list
Send the eight items to each bidder in the same format and compare what comes back, not what is promised on a call. Answers that name your product, your samples and your measurement method show a supplier preparing for your line. Answers that repeat marketing phrases show a standard machine being offered at your cost.
If you want the deliverables reviewed against an actual equipment proposal, contact Shenzhen PowerDe Automation Precision Equipment Co., Ltd. with your process input sheet, and ask for the acceptance protocol draft in the first reply.
