SMT + THT
Printing, placement, insertion, soldering, inspection, and handling
Manufacturer direct
We match machines by line takt, PCB size, component class, and factory automation level.
Complete line scope
SMT, THT, wave soldering, selective soldering, board handling, SPI/AOI, and test transfer.
Export-ready support
Overseas installation guidance, operator training, remote support, and spare parts planning.
ROI-led configuration
We avoid overbuilding. The line should fit current output while leaving practical expansion room.
Line architecture
We design the full PCB assembly line, not isolated machines.
The right setup depends on product mix, output target, PCB size, component difficulty, quality level, budget, and future growth.
THT Section
Auto insertion for radial, axial, or odd-form parts, or manual assist when volume and mix make it smarter.
Wave / Selective Soldering
Wave soldering for stable THT flow; selective soldering when mixed SMT/THT board constraints require precision.
Board Handling
Magazine loaders, conveyors, buffers, inverters, NG/OK sorting, depaneling, and test-station transfer.
Equipment visuals
Real machine images help buyers understand capability fast.
Images are sourced from Southern Machinery's photo library. During quotation, we match specific models and quantities to your PCB size, components, capacity target, and budget.
THT auto insertion line
Useful for radial components, odd-form insertion, and higher THT output targets.
Process support equipment
Cleaning, coating, curing, ESD, and material support can be planned into the line.
Back-end automation
Depaneling, testing, buffering, and transfer affect real throughput, not just placement speed.
Product catalog
Embed the live machine catalog directly into the site.
Buyers can browse SMT, THT, wave soldering, board handling, inspection, process support, and feeder/nozzle resources without leaving the page.
Machine working videos
Show the machine in motion before the first meeting.
The video board brings together YouTube working videos for sales follow-up, buyer evaluation, and internal factory discussions.
Capacity fit
Different volumes need different line choices.
A high-mix pilot line should stay flexible. A mass-production line should protect takt time. Both under-automation and over-automation waste money.
Prototype / High mix
Flexible pilot line
Semi-auto printer, one medium-speed placer, compact reflow, and manual or semi-auto THT support.
Medium volume
Balanced automatic line
Auto printer, one or two pick-and-place machines, 8-10 zone reflow, wave soldering, and basic inline inspection.
Mass production
High-output factory line
High-speed placement, full board handling, SPI/AOI, auto insertion, and high-capacity soldering with expansion room.
RFQ inputs
Send four details and we can shape the first line plan.
You do not need a perfect specification at the start. With the basics, we can calculate capacity, bottlenecks, and a realistic configuration range.
- 01Product type and PCB sizeFor example LED drivers, power supplies, or consumer electronics, plus L x W, thickness, and panelization.
- 02Monthly or shift outputPieces per month, shifts per day, and hours per shift let us estimate CPH and boards per hour.
- 03Main component classes0402/0201, QFN/BGA, connectors, transformers, heatsinks, radial/axial parts, and odd-form THT parts all matter.
- 04Budget and automation levelSemi-auto, standard automatic, and high-speed automatic lines have very different CapEx and staffing trade-offs.
