Shenhua SME-6140 Inline DI Water PCBA Washer

The Shenhua SME-6140 is an inline PCBA washer for cleaning assembled boards after SMT or through-hole soldering. Shenhua lists a 600 mm mesh belt and a maximum board width of 550 mm for this configuration. The line transfers boards through wash and rinse sections, then uses air knives and heated air to remove water before discharge.

DI water supply and monitoring

The SME-6140 has adjustable upper and lower spray pressure and monitors rinse-water resistivity. Its water circuit uses overflow from later sections toward earlier sections. Shenhua lists DI water consumption of 400–800 L/h for the published configuration, an important figure when sizing water production and drainage. Check the utility schedule for the supplied unit alongside the water demand from the rest of the site.

Start process trials with the soldered assembly and flux you actually run. Water-soluble residues are a direct use case for DI water washing. For rosin or no-clean flux, share the exact material and cleanliness requirement so the wash chemistry and rinse process can be validated on your board. When requesting a quote from GEEKVALUE, include panel width, component height, conveyor interface and available DI supply. Those details determine whether the published layout fits your production and facility.
