Procurement Recommendation

China-based PCB factories offering HASL lead-free PCBA should provide one-stop capabilities: from Gerber review and DFM feedback to SMT/THT assembly, AOI, and functional testing. Confirm they use SAC305 solder alloy, comply with IPC-A-610 Class 2, and offer RoHS/REACH documentation. Ideal for startups or SMEs needing rapid prototyping to volume production. Avoid shops quoting ultra-low prices without disclosing panelization or stencil costs—request a detailed NRE breakdown and sample board before committing to large batches. (for reference only)
