How do you calculate waterproofing yield rate?

Divide the number of drones that passed the ingress test by the total batch and multiply by 100. With 8 passing units out of 250 the yield is 3.2%, which sits 91.8 points below a 95% target — a clear signal the sealing process is failing.

What is a good waterproofing yield for IP-rated drones?

A controlled sealing and gasketing process should pass 95%+ of units on ingress test. Anything in the single or double digits, like the 3.2% default, indicates a systemic seal, gasket, or cure problem rather than random variation.

Does the pass count mean passes or failures?

In this calculator the count is the units meeting the waterproofing criterion — the passes. If you record failures instead, you must convert to passes (total minus failures) before entering, or the yield will be inverted.

Why is my waterproofing yield so far below target?

A yield of 3.2% against a 95% target — a 91.8-point gap — almost always means a batch-wide root cause: a misseated gasket batch, an under-cured sealant, wrong fastener torque, or a housing dimensional drift, not scattered one-off failures.

How is waterproofing yield different from first-pass yield?

Waterproofing yield is specific to the ingress test and reflects seal integrity, while overall first-pass yield spans all functional and cosmetic checks. A drone can flash and fly perfectly yet still fail waterproofing, so the two are tracked separately.

How many units should I test for a valid waterproofing yield?

The ratio itself works at any size, but confidence does not — a 250-unit batch gives a stable read, while judging a seal change on 5 units is noise. For destructive or slow immersion tests, use a defined sampling plan rather than one-off spot checks.

UAV & Drone Manufacturing calculator

Waterproofing Yield Calculator

Weatherized and IP-rated drones must survive an ingress test — spray, immersion, or pressure-decay — before they ship, and the waterproofing yield rate tells you what share of a batch actually passes. This calculator takes the count of units meeting the waterproofing criterion against the total batch and returns the yield percentage plus the gap to your target rate, so quality and process engineers can see at a glance whether a sealing or gasketing process is under control. It matters because ingress failures are expensive and often invisible until the field: a low waterproofing yield points straight at seal design, gasket seating, adhesive cure, or fastener torque before those escapes reach a customer's flight in the rain.

What this calculator does

Estimate waterproofing yield for uav and drone manufacturing using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.
Use it when waterproofing yield in uav and drone manufacturing needs a clean rate and gap-to-target you can put on a tier board.
It computes the waterproofing yield rate as pass count divided by total batch times 100, and reports the point gap between that rate and your target.

Formula used

Waterproofing yield rate = waterproofing yield count ÷ total waterproofing yield population × 100
Waterproofing yield gap to target = waterproofing yield rate - target waterproofing yield rate

Inputs explained

Drones passing the ingress test:
Drones in the waterproofing test batch:
Target waterproofing pass rate:

How to use the result

Use it after an ingress-protection test run to gauge how a sealing process is performing against a target IP pass rate.
It is a simple ratio and knows nothing about failure mode, sample size, or test severity — a high yield on a lax spray test can still hide field failures under real immersion.

Current U.S. benchmarks

Global copper trades at $13,484 per tonne (IMF via FRED, May 2026), up 41.5% in a year, and U.S. industrial electricity averages 8.66 cents per kWh. Both feed electrified-hardware unit economics.
