Gather all required components (PCBs, ICs, resistors, capacitors, etc.) and verify their specifications before assembly, 100% match customer’s requirement.
Pre-bake moisture-sensitive components (MSDs) at controlled temperatures (typically 125°C for 8-24 hours) to prevent delamination or popcorn effect during high-temperature soldering.
Engrave serial numbers, barcodes, or logos on PCBs for traceability and identification.
Place PCBs onto the production conveyor to begin the automated assembly process.
Gather all required components (PCBs, ICs, resistors, capacitors, etc.) and verify their specifications before assembly, 100% match customer’s requirement.
Check for proper solder paste deposition (volume, alignment) to prevent soldering defects.
Use pick-and-place machines to mount small surface-mount (SMD) components (e.g., resistors, capacitors) at high speed.
Place larger or irregularly shaped SMD components (e.g., connectors, BGAs) that require precise handling.
Scan for missing, misaligned, or defective components before soldering.
Melt solder paste in a controlled oven to permanently attach SMD components to the PCB.
Inspect solder joints and component placement after reflow to catch defects like bridging or tombstoning.
Perform comprehensive verification (dimensional, electrical, visual) on the initial production unit against engineering specifications before full batch release.
Insert through-hole components (e.g., connectors, large capacitors) manually or via machines.
Verify correct placement of through-hole components before wave soldering.
Solder through-hole components by passing the PCB over a molten solder wave.
Manually repair poor solder joints (e.g., cold solder, bridges) after wave soldering.
Hand-solder components that cannot withstand high-temperature processes (e.g., heat-sensitive parts)
Conduct a comprehensive inspection to ensure all components and solder joints meet quality standards.
Perform functional tests (e.g., power-on, signal checks) to validate the board’s performance.
Apply a protective layer (e.g., silicone, acrylic) to prevent corrosion, moisture, and dust damage.

Partner with Mustar for peace of mind and production success.
We partnered with Mustar for a new generation of our medical monitoring devices. From the initial DFM suggestions to the final batch testing, the team was proactive, highly responsive, and technically skilled. The assembled PCBs passed every compliance check in our EU lab. Most importantly, they met our tight 25-day timeline without compromising quality. Mustar truly acts as an extension of our in-house team.
Mustar has been our go-to PCBA supplier since 2019 for multiple vehicle control unit projects. They consistently deliver high-quality boards that meet our IATF 16949 and high-temp automotive specs. Their flexibility on low-MOQ sampling and speed of prototyping helped us accelerate product launches by 20%. With Mustar, we don’t just buy PCBA—we get dependable technical partnership.
Our IoT-based home automation startup needed a vendor who could handle full turnkey service, from layout review to firmware preloading. Mustar handled it all smoothly. Their engineering team helped us redesign a section of the PCB to improve signal stability, and their sourcing team even secured hard-to-find Wi-Fi modules during shortages. We’ve scaled up to 80,000+ units with zero major quality issues.
