Surface Mount Technology (SMT) encompasses a series of assembly processes, which include single-sided assembly, single-sided mixed assembly, double-sided assembly, and double-sided mixed assembly. The fundamental components of these processes consist of solder paste printing (or dispensing), component placement (curing), reflow soldering, cleaning, and subsequent inspection and REWORK . Prosedur terperinci diuraikan sebagai berikut:
Perakitan Single-Sidate:
- Inspeksi Masuk
- Pencetakan pasta solder
- Aplikasi pasta solder (lem merah)
- Penempatan Komponen
- reflow (curing)
- Membersihkan
- Inspeksi
- pengerjaan ulang
Perakitan campuran satu sisi:
- Inspeksi Masuk
- Pencetakan pasta solder A-side (lem merah)
- Penempatan Komponen
- Reflow A-Side (Curing)
- Membersihkan

The essential elements of SMT assembly include solder paste printing (or dispensing), component placement (curing), reflow soldering, cleaning, and inspection and rework. The materials utilized in these processes comprise standard circuit boards (rigid boards) and flexible circuit boards (soft boards).
The processing methods encompass PCB soldering, lead-free SMT surface mount assembly, through-hole assembly, SMD surface mounting, BGA soldering, BGA ball placement, BGA assembly, and surface mount packaging. The variety of products is extensive, featuring mobile circuit boards, automotive diagnostic tools, ultrasound devices, set-top boxes, routers, network media players, dash cameras, programmable logic pengontrol (PLC), pengontrol tampilan, analisis spektrum, alat penata rambut, dan banyak lagi .
