Lorsque vous envoyez vos fichiers Gerber et votre nomenclature à un partenaire fabricant, la première question est toujours la même: Combien de temps avant de recevoir les planches finies?
The straightforward answer: PCBA is a fully customized process, so there is no single lead-time number. But transparency matters — and that starts with understanding what drives the timeline.
The Three Stages of PCBA Production
1. PCB Fabrication — 2 à 5 Semaines
Your bare board is the foundation. Standard laminates are readily available and fabrication moves quickly. Cependant, designs requiring special or high-performance laminates may face material shortages, extending this phase to several weeks. Early specification of material requirements helps us lock in supply sooner.
2. Component Sourcing — 2 Weeks to 50 Semaines
This is the most variable — and most unpredictable — stage. The majority of standard components arrive within two weeks. But hard-to-find, obsolete, or high-value parts can stretch lead times to 20, 50, or more weeks. This single factor often determines your overall project timeline.
3. PCB Assembly — 2 à 4 Jours
Once bare boards and all components are on the production line, assembly for 500 to several thousand pieces takes just 2 à 4 jours, plus final inspection and packaging. Assembly is the fastest part of the process — the real drivers are PCB fabrication and component availability.
How We Shorten the Total Cycle
The key to reducing PCBA lead time is not in speeding up assembly — it is in starting earlier and working in parallel.
- Parallel front-loading: With complete Gerber files and BOM in hand, we initiate PCB fabrication and long-lead component sourcing simultaneously rather than sequentially.
- Vendor-Managed Inventory (VMI): For critical, high-value, long-lead components, we maintain pre-stocked inventory under a VMI arrangement. When your order drops, those parts are already on our shelf — production starts immediately, with no sourcing delay.
- Material-ready delivery promise: Once all materials are on hand, we deliver finished PCBA boards in 7 à 10 jours.
The Bottom Line
The most effective way to cut your PCBA lead time is simple: start PCB fabrication early and pre-build long-lead components. Every week saved in sourcing is a week shaved off your final delivery.
