We solder components on the circuit board, from tiny chips to large connectors and BGA parts.
Our company has several experienced hand soldering staff members. We can hand solder chip sizes up to 0402. We specialize in the assembly and rework of chip components, as well as QFPs and QFNs with thermal pads, and BGAs (up to 3000 pins). For SMD connector components such as those from Samtec, we solder them using infrared (IR) equipment, so there is no worry about the connector resin melting. For leadless components, we conduct inspections using X-ray (with a 60-degree tilt) after assembly. If you are short on labor and cannot meet soldering deadlines, or if you have a mix of eutectic (lead-containing) and lead-free components, please feel free to use our services. Please do not hesitate to consult us for projects that have been declined by other companies.

Company information
The impetus for our work on BGA rework was "environmental protection." Starting around 2002, we began to see a significant number of circuit board repairs that were impossible to fix while conducting mobile phone repair operations. When BGA (IC) was incorporated into mobile phones, adhesive (underfill) was used as a measure to prevent solder peeling. This adhesive reinforces the bonding between the circuit board and the IC, but due to aging and usage conditions such as drops, it can surprisingly crack easily. Later, these cracks can erode the solder of the IC, leading to functional failures. Since mobile phone circuit boards have many functions, the disposal cost for a single unit can be enormous. If IC replacement becomes possible, repairs can be conducted with just the cost of the IC and its replacement, allowing other components to be reused, which we believe connects this recycling technology to "environmental protection." Our company has been committed to creating a more environmentally friendly world through circuit board modification, repair, BGA reballing, and component regeneration long before the term SDGs became widely recognized, emphasizing the importance of the global environment.
