A 90-Minute Remote Factory Audit for IPL Devices

A remote factory audit is worth doing if you run it as one continuous, unedited video with a fixed route and a random unit opened on camera. Book 90 minutes. Ask for a single call, one phone, no cuts, walking from raw material storage to packing. The constraint that makes it useful is the absence of editing, not the resolution of the camera.

I’m Eric, co-founder of iShine. We’ve hosted these calls for brands who couldn’t fly, and we’ve run them on suppliers we were considering ourselves.

Most brands do this badly. They get sent a 40-second clip of a clean assembly line, shot from an angle that never shows the floor, and call it diligence.

Why the unedited walk beats the showroom

A showroom tells you what the factory wants you to see. An unedited walk tells you what the route between two rooms looks like, and that’s where the information is.

Does the person holding the phone know where the incoming inspection bench is without asking someone? Do they walk past a pallet of returns and avoid it? Does the corridor have work-in-progress sitting on the floor, which means the line is backed up? None of that survives editing, and all of it is free to observe.

Ask for the call to be scheduled during a production shift, not at shift change and not on a Sunday. A factory that can only show you an empty floor is telling you something.

The audit route

Give them the walking order in advance so nobody has to improvise.

Start in raw material storage — housings, PCBA, lamps, packaging in their cartons. Then the SMT or PCBA area, then sub-assembly, then final assembly, then the aging test rack, then packing, then the finished goods area. Then ask them to come back to the reject bin at the end.

That order matters. Raw material first shows you whether the parts exist before the build starts. The reject bin last shows you whether they’ll show it to you once they’ve relaxed.

Five things to ask them to show on camera

An in-process unit, opened. Not a finished one. Ask them to pick a unit that’s half-built and show the inside: the capacitor bank, the lamp mount, the heat path. You’re checking whether the internals match the BOM they sent, and whether the assembly looks like it was designed or improvised.

The aging test rack, running. Ask how long units sit on it and what the pass criteria are. A rack that’s empty during a production shift means either nothing is being aged or the batch just finished. Follow up with “how many units on the rack right now, and when did that batch start.”

The calibration sticker on the energy measurement rig. There’s a meter somewhere in that factory that decides whether a unit outputs the J/cm² it claims. Ask to see its calibration date. An expired sticker is common and it means every measurement since then is unverified.

The incoming inspection bench, with its sampling plan. Ask to see the form they fill in when a component batch arrives. A bench with no paperwork is a bench that exists for visitors.

The reject bin. Ask what percentage of units get pulled and where they go. Every factory has one. A factory that claims zero defects is either very good or very practiced at hiding the bin.

Three questions a trading company cannot answer live

These are designed so that a real factory can answer from memory and a middleman cannot.

“Which mold made this housing, and what’s the tooling number?” Someone on the floor knows. A trading company has to go ask someone, which takes time and often produces a vague answer.

“What’s the cycle time on the assembly station we’re looking at right now?” A production manager answers instantly. A middleman guesses.

“Walk me to the QC office and show me last week’s first-article records.” The walk is the test. If they can’t find the office without asking, they don’t work there.

What a video audit cannot verify

Be honest about the boundary. A video call cannot tell you real monthly capacity, wage levels, staff turnover, or whether the line you’re watching runs at that pace every day.

Ask for records instead: three months of production output by model, a list of active customers by product category (names redacted is fine), and the number of production staff on the payroll. Then compare those records to what you saw. If they claim 30,000 units a month and the packing area has four people, do the arithmetic.

Some of what you’re checking has a paper trail already. In the US, 21 CFR 820 requires device master records and complaint files; the aging test and the output measurements you’re watching exist to demonstrate EN IEC 60335-2-23 conformity, with the photobiological side running to IEC 62471. Ask for those records rather than a description of them. And check the facility itself in the FDA establishment listing database before the call, so you know which legal entity is supposed to be on the other end of the video.

a Canton Fair visit covers what a factory’s claims look like when you’re standing in it, which is a useful calibration for the video version.

The one-page sheet

Send this to the supplier before the call, so nobody is surprised.

Item	What to capture	Red flag
Route	Confirmed order and timing	Refusal to walk a section
Raw material	Cartons labeled, quantities visible	Empty storage during a build
PCBA area	SMT line running or stocked	”That’s at our partner factory”
In-process unit	Internals shown, matches BOM	Refusal to open a unit
Aging rack	Units on rack, duration, pass rate	Empty rack, no records
Calibration	Sticker date on the energy rig	Expired date
Incoming inspection	Form with sampling plan	No paperwork
Reject bin	Volume and disposition	”We have no defects”
Records	Output by month, headcount	Numbers that don’t reconcile

Ninety minutes, one call, and a sheet with nine rows. That’s a real audit. It won’t replace standing in the building, but it will get you most of the way, and it costs a video call instead of a flight.

If you want to run this against us, book a call and we’ll do the walk on a production day. If you’d rather start with paperwork, the seven documents to request are the faster filter, and how quality control actually runs in IPL manufacturing explains what the aging rack is for.
