Magazine loaders, unloaders, NG/OK dual unloaders, vacuum loaders, conveyors, shuttles, buffers, flippers and turn conveyors ā engineered in Shenzhen to link your SMT, THT and wave-soldering line into one continuous, low-labor, SMEMA-ready flow.
Specs sourced from Southern Machinery PCB Board Handling Equipment Catalog 2023. Custom widths, pitches, lengths and SMEMA / Ethernet / AGV options on request.
Manual loading, hand-to-hand panel transfer, mis-orientation and NG mix-ups silently steal capacity from EMS factories. Southern Machinery BHS solves the seven most common pain points with one modular, SMEMA-compatible toolkit.
Replace manual loading with SLD250/330/390 magazine loaders or SLC0W/330W/460W bare-board destackers ā 6 sec load cycle, 30 sec magazine exchange, full-cover guarding.
SBH250/330/390/460 NG-OK dual unloaders and SNL390 NG/OK separator route reject boards into a dedicated 10-slot magazine while OK boards keep flowing ā no stop-line, no rework confusion.
SVL330 vacuum loader handles 1.5 m LED long boards. SPD330/460 shuttle conveyors compensate distance between machines without rebuilding the line.
SBM390 buffer stocker (20 slots, FIFO/LIFO/Go-thru) absorbs upstream-downstream speed mismatch; SBF460 / Sub460 conveyors handle wave-solder input/output without warping.
SBI460 / S-K390 PCB inverters flip panels for second-side processing while keeping SMEMA hand-off so AOI and reflow stages stay synchronized.
SCN330 turn conveyor changes flow direction; SAC460 telescopic gate conveyor opens an automatic passage so workers and AGVs cross the line without breaking SMEMA.
Mix and match below to build a fully SMEMA-linked board-handling chain ā from bare-board feeding through wave-solder output to NG/OK sorting.

Engineers onsite or remote for commissioning, SMEMA hand-off testing and operator training on the 9-inch HMI.
Belt, sensor, magazine, servo and HMI parts shipped from Shenzhen ā typical dispatch within 1 working day.
237+ EMS customers across SE Asia, South Asia, Middle East, Mexico and Eastern Europe. CE & RoHS reports on file.
A typical fully-linked SMT line uses: 1Ć magazine loader (e.g. SLD390) at the line front ā printer ā mounter ā reflow ā 1Ć SBM390 buffer ā AOI ā 1Ć SBH390 NG/OK dual unloader at the line end, plus inline S-460D conveyors and an SCN330 turn or SAC460 telescopic gate where the floor layout requires it. We provide a free line drawing based on your machine list.
Yes. Standard SMEMA hand-shake is built in on every Southern Machinery BHS unit. Optional Ethernet, AGV communication and MES interface are available. We have specific retrofit packages for legacy UIC AI lines and JUKI lines ā see BHS Retrofit UIC.pdf and the JUKI sales-meeting deck.
Yes. The SVL330 vacuum loader is purpose-built for 1.5 m LED long boards, and the conveyor "E" series (S-350E / S-460E with optional inspection light) provides 1.5 m sections so you can build a long-board line end-to-end without third-party parts.
We have full CE certification reports on file for: PCB Loader, PCB Unloader, PCB Conveyor & Buffer, and the general PCB Board Handling Machine category, plus the matching RoHS reports. Reports are issued by accredited third-party labs and can be sent as full PDF attachments alongside our quotation.
SBM390 has 20 slots at 25 mm clearance, ~12 sec cycle, and supports four programmable modes ā FIFO, LIFO, NG/OK and Go-thru. The dedicated NG/OK Buffer Machine S-390KGBF can additionally store up to 20 NG boards from SPI/AOI for false-call inspection.
SBH-series dual unloaders use a shuttle car to route boards into 50 OK slots or 10 NG slots based on the AOI signal, with pitch selectable at 10 / 20 / 30 / 40 mm. A normal unloader (SUL / SULD) just stacks every board into one magazine ā fine for end-of-line packing, not for inline rework.
Yes ā that is exactly what we built the BHS retrofit packages for. Typical retrofit replaces the manual loading station with SLD / SLC, links the AI machine into a 920 mm transmission-height conveyor chain, and adds a buffer + NG/OK unloader at the back end. Layout, mechanical interface drawing and bill of material can be quoted within one week.
