PCB manufacturing consists of PCB fabrication and PCB assembly. In most cases, rigid flex PCB doesn’t have large or even mid-volume order like rigid PCB, which means it is not cost-effective and efficient to hire a separate assembler. By working with fabricator offering turnkey assembly service, you could speed up the delivery and lower communication cost caused by multi vendors. As some firms only focus on one service and not the other, so while you look for fabricator, you might want to confirm if they provide assembly service as well.
Another important info to collect is their capability. Not just brief intro of what they offer, but also detailed description on key parameters like final thickness, impedeance control, min trace/width,copper thickness, aspect ratio, min hole size and available laminates. These details could help you assess how much they are good at building rigid flex PCB. Of course, if you are worried about hype, you could pick a few parameters and let them send you past cases for reference. After noting down these, you need to go further verifying if they are capable of volume production. A lot of manufacturers only able to deliver several pieces of rigid flex PCB samples after scrap numerous boards. It will be a disaster if you let them process your volume order even small run.
The last consideration is communication. It is called out becasue I assume you are looking for China rigid flex PCB manufatcurer which has time-zone and language difference with you. And PCB project is the kind of transaction that entails many updates and revisions. So extra care need to be given to this factor when you are choosing supplier. This part is easy to identify during your email communication or phone call conversation.
In summary, when you touch base with a new rigid flex PCB supplier, ask them below questions:
Though above is not an all-inclusive list, but with them, you can make a strong start on new rigid flex PCB supplier query.
