A TGV alignment packaging machine is rarely bought on a datasheet alone. It is usually bought through a commissioning agreement: the buyer supplies glass substrates, PI film and a target process window, and the supplier proves on-site that the line can align, package and debubble those materials repeatably. In our experience, the difference between a machine that clears acceptance and one that stalls in the field comes down to what both sides agree on before delivery. The package below is the checklist we use when a customer issues the RFQ for a TGV alignment packaging machine, and we recommend putting every item in writing.
1. Process and material specifications from the buyer
Before any equipment is proposed, the machine builder needs the actual workpieces. Send reference glass plates with their through-glass-via geometry, the PI film or soft film you intend to package, and the dimensional tolerances you will be judged against, including total thickness, bow and warpage, and handling limits. Our own TGV alignment packaging machine solution covers glass plate and PI-film soft alignment packaging, and it is built around selectable process recipes intended to reduce alignment bubbles — but recipe selection is a joint exercise, so the materials have to be characterized first.
2. Machine capability and configuration list
Ask the supplier to state, item by item, how the machine meets your specifications: the alignment method and achievable alignment accuracy for your substrate size, the heating and press parameters in the ranges your materials require, whether recipes are stored per product and how many, and what vision or alignment hardware is used. Also request a full bill of materials for the main components — heaters, pumps, sensors, valves, PLC and motion parts — with brands and models. When a subassembly needs replacing at 2 a.m., a brand name in a document saves hours.
3. Acceptance criteria and test protocol
Agree on the pass/fail rules before the machine ships. Define the sample size for the alignment and packaging trial, how alignment accuracy will be measured, and how bubbles are judged — acceptable size, count and location for each product. We suggest a two-stage protocol: a factory acceptance test on your materials before shipment, and an on-site repeat after installation. Anything not defined as a measurable number will not be defensible later.
4. Documentation package
Ask for a complete set of drawings and manuals in the language your engineers actually read: mechanical and electrical drawings, pneumatic and hydraulic circuits, wiring diagrams, the PLC or HMI operation manual, the maintenance manual with consumable part numbers and recommended replacement intervals, and a consumable and spare-parts list with lead times. For process equipment, also request the recipe documentation — what each parameter means, its safe range, and how changes are recorded — so your team can adjust a recipe without calling the supplier.
5. Installation, utilities and site preparation
The supplier should provide a site preparation sheet covering footprint and level tolerance, floor loading, power supply capacity and quality, compressed air, exhaust or venting, water if used, and ambient temperature and cleanliness limits. Confirm who is responsible for rigging, lifting and connecting utilities, and whether the machine needs to be down for calibration after transport. Our semiconductor process equipment is built to order, so we issue these requirements with the contract rather than after the machine arrives.
6. Training and knowledge transfer
Decide who gets trained, on what, and where. At minimum, operator training on the HMI, recipes and alarms; engineer training on parameter adjustment, first-article checks and troubleshooting; and maintenance training on consumables, alignment checks and safety lockout. Ask for the training materials as files, not just sessions, and for a record of what each trainee covered. A process that only one supplier engineer understands is a process that stops when they leave.
7. Warranty, service response and spare parts
The handover package should state the warranty term and what it excludes, how a fault is reported, the guaranteed response time, whether a service visit or a remote session comes first, and which parts are held as spares and by whom. For consumables, agree on unit prices and lead times, because those costs, not the machine price, drive the operating budget over the years.
8. Commercial and after-sales documents
Close the file with the signed specification, the test reports from both acceptance stages, the serial number and shipment records, and the contact list for after-sales support. These documents are what your procurement and quality teams will ask for at the first audit, and they make the next purchase — a second line, or an upgrade for a new product — a much shorter negotiation.
If you are evaluating TGV packaging equipment now, send us your substrates and target process window and we will confirm what the machine can achieve on them before you commit. See our semiconductor process equipment range, or contact Shenzhen PowerDe Automation Precision Equipment, intelligent cleaning equipment manufacturer and advanced automation supplier, to arrange a trial.
