Precision BGA Solder Ball Placement｜Low-Void No-Clean Process for Advanced Chip Back-End Processing
Release time:2026-04-22
Against the backdrop of rapid development in chip back-end processing and semiconductor post-packaging, high-end precision chips impose extremely stringent requirements on the accuracy, yield, stability and production efficiency of the BGA ball placement process. Conventional ball mounting technologies are prone to bridging, ball misalignment, excessive voiding, complicated processes and flux residues, making them incompatible with high-end applications such as fine-pitch chip packaging and advanced packaging processing. Based on our proprietary invention patent for process method – A Low-Void No-Clean Solder Ball Placement Method for Fine-Pitch BGA Chips, we focus on core precision chip ball mounting and comprehensively optimize the entire chip back-end finishing process, providing customers with a one-stop, high-precision, high-efficiency and high-reliability BGA packaging and ball mounting solution.
This patented process targets the manufacturing challenges of 0.3mm ultra-fine pitch BGA chips and breaks through bottlenecks of traditional technologies through three core technical optimizations in the chip ball mounting process. It adopts quantitative temperature-controlled flux spraying to precisely control spray volume and temperature, avoiding uneven application and excess residues. Paired with a solder ball precision positioning system, it achieves micron-level alignment and eliminates typical defects such as solder bridging, ball misalignment and missing balls in fine-pitch applications. Meanwhile, optimized lead-free reflow soldering profiles precisely control temperature ramp-up, soaking and cooling, significantly reducing solder voiding rate and fundamentally improving chip soldering reliability and package stability.
Compared with conventional ball mounting processes, the core advantage of our patented technology lies in its eco-friendly no-clean process. Featuring an environmentally friendly no-clean flux system, it eliminates the need for post-process chip cleaning, saving equipment, chemical consumption and labor costs, streamlining chip post-processing steps, greatly improving mass production efficiency and shortening packaging cycle time. It also reduces contamination risks and potential chip damage from cleaning, aligning with green intelligent manufacturing standards in the semiconductor industry and enabling both high-efficiency processing and sustainable production.
The patented process performs excellently across full-scenario applications including high-end chip packaging, precision semiconductor processing, chip reballing, BGA rework ball placement and chip bump preparation. It fully supports high-precision integrated circuits, automotive chips, industrial control chips, AI computing chips and other high-end products for fine-pitch ball mounting, effectively resolving fine-pitch manufacturing difficulties, steadily improving production yield, lowering process defect rate and enhancing package final yield and long-term operational stability.
With years of expertise in semiconductor finishing and chip packaging back-end processing, we rely on proprietary patented technologies and standardized precision process control to specialize in BGA ball placement services and chip back-end packaging processing. We implement full-process quality control covering process parameter optimization, precision alignment processing and final reliability testing, supporting both custom small-batch precision processing and large-volume mass production.
Moving forward, we will continue to invest in R&D and iteration of advanced ball mounting technologies and further optimize the chip back-end processing technology system. With patented core capabilities, we break through technical barriers and deliver more accurate, efficient, eco-friendly and stable precision chip ball mounting services for the high-end semiconductor packaging industry, helping customers enhance their core product competitiveness.
