The right cleaner is the one that matches your board volume and line layout — inline wins on throughput, offline wins on flexibility, and both still depend on the same water and pressure fundamentals.
Which Cleaner Fits Your Line Layout?
Inline cleaners move boards through on a conveyor, tied directly into the SMT line. Offline (batch or standalone) cleaners sit beside the line and process boards in loads. The choice is rarely about cleaning power and almost always about flow.
High-volume, repeatable production with a steady board mix favors inline. Low volume, frequent changeovers, rework batches, and prototyping favor offline, where you are not paying for a conveyor that idles between jobs.
What Does an Inline Cleaner Give You?
An inline machine cleans as fast as the line feeds it. Throughput stays consistent because every board sees the same dwell time, spray pattern, and rinse. That repeatability is why automotive and medical lines standardize on inline.
The cost is commitment. Inline demands floor space, a fixed line position, and continuous chemistry and DI water supply. Reconfiguring the line later is expensive.
What Does an Offline Cleaner Give You?
An offline cleaner handles a mixed basket — a rework lot, a low-run medical board, a prototype panel — without disturbing the main line. Capital cost is lower, and the machine earns its place even at low utilization.
The trade-off is labor and cadence. Someone loads and unloads. Batch variation means you tune parameters per basket, not once for the whole shift.
Which Cleaning Fundamentals Do Both Share?
Whichever form you pick, the cleaning physics does not change. DI water resistivity in the 15–18 MΩ·cm range carries the rinse; spray pressure in the 15–30 PSI band removes residue without threatening delicate parts. Skimp on either and the form factor will not save you.
