Questions & Answers
1.Do you offer DFM support during the design stage?
Yes, MOKOPCB can assist with DFM checks in the design process to ensure design reliability and reduce overall production time and cost.
2.Does MOKOPCB provide support for component selection?
Absolutely. We offer detailed technical documentation for each product, including specs and assembly guidelines.
3.Why do most rigid-flex circuit boards use FR-4 for the rigid part?
FR-4 offers many benefits, including low cost, high thermal resistance, excellent insulation, and mechanical strength. It is ideal for durable and reliable multilayer designs in many industries.
4.What is the common stack-up of 6 layer rigid flex PCB?
This is a common stack-up: 2L rigid + 2L flex + 2L rigid. Generally, the flex layers are in the center, which are easy to manufacture and low cost.
5.What are the benefits of 6 layer rigid flex boards?
A 6-layer rigid-flex PCB offers improved connection reliability, reduced part count, and supports high-density designs. It is ideal for compact, lightweight, and high-performance applications.
