Define commissioning for this equipment, and who signs it
A semiconductor or display line contains machines that are expensive to stop, so commissioning of one new unit has to be defined as something narrower than "it runs". Write down the four things this machine must demonstrate before production accepts it: it meets its own process specification, it is safe with the utilities it is connected to, it exchanges product and signals correctly with the stations on either side, and it can be operated and recovered by your team. Then name one person who signs each of those four. Without that split, a handover becomes one big yes-or-no argument, and the small real problems get waved through with the rest.
Commission in four passes, and keep them separate
Pass 1 — the machine alone. Installed, connected to its utilities, run without product. This is where you verify the safety functions and the process window, and where the machine's own protection functions should be tested deliberately rather than trusted. On PowerDe equipment the protective functions are listed in the product copy — for the Fixed Steam Cleaning Machine HW02, the page lists leakage, short-circuit, high-temperature, high-voltage and water-shortage protection, plus a vacuum function. Whatever the machine, record the value at which each protection actually acts.
Pass 2 — the interfaces. The machine is fed by the station in front of it and hands product to the one behind. Most handover disputes start here, because both suppliers are right about their own machine and nobody owns the interface. Test signals, timing handshake, physical alignment and jam recovery across the boundary, and write down which machine stops when the other one stops.
Pass 3 — the process. Real product, real recipe, sustained for long enough to expose drift and consumable life. Alignment and bonding processes are settings-sensitive, so record the recipe that passed, not just that it passed.
Pass 4 — the people. Operators run it without the supplier's engineer standing there, including the fault cases: what each alarm means, what to do, what must never be bypassed, and when to call. A machine your team cannot recover from a fault has not been commissioned, whatever the measurements say.
Build the handover package as you go, not at the end
The package a plant should receive is boring and specific: drawings at the revision actually installed; wiring and utility diagrams; the parameter and recipe list with factory values; the as-built record of anything changed on site; the supplier's own test report; the consumables and spares list with who stocks them; and the operating and fault instructions in the language your operators read. Collecting this during the four passes costs almost nothing. Collecting it afterwards means someone reconstructing from memory what the machine was set to.
Agree what is still open, and by when
Almost no handover closes with zero defects, so make the open list part of the document rather than part of a promise. Each item needs an owner, a target date and the condition under which it is considered closed. Then state what the supplier still owes you after handover: response time, warranty scope, and what counts as a supplier fault rather than a site fault. Sign the handover against the closed list, not against the calendar.
Who at PowerDe works with this kind of package
PowerDe builds semiconductor process equipment — vacuum lamination, bonding and debubbling machines — and its engineering services also cover customization and integrated engineering-team support, which is the scope that produces handover documentation as part of the job rather than as an afterthought. If you are taking delivery of a machine, send your four pass definitions and your utilities list to the team before installation and ask what the returned package will contain.
