Shenzhen JLC: High-Layer and HDI PCBs Key to Future Growth

The significance here is less about capacity and more about bundling: Shenzhen JLC is describing PCB leadership as a lever that pulls customers into PCBA, with penetration as the metric that reveals how well that lever works. High-layer-count and HDI boards matter because they tend to sit in more demanding applications, so the stated direction implies a shift up the value chain rather than pure volume. The open question is whether PCBA penetration keeps rising as board complexity increases, since that conversion rate is the clearest read on whether the entry-point strategy is holding.
