FREQUENTLY ASKED QUESTIONS

Are you looking for answers to your questions about ordering PCBs? In our FAQ you will find all the information you need about the types of PCBs, the collaboration process, lead times and the technical specifications of the PCBs we offer.

We provide a full range of printed circuit boards: single-sided, double-sided, multilayer, HDI, flexible and rigid-flex, IMS (metal core) as well as RF and microwave PCBs.

Our lead times include:

  • Express Prototypes: 6-8 business days
  • Standard Prototypes: 10-12 business days
  • Small-scale Production: 10-14 business days
  • Large-scale Production: 14-18 business days

Each lead time is tailored to the specifics of your project.

PROPCB offers a minimum trace width of 3 mils and a minimum trace spacing of 3 mils.

We offer materials such as FR4, Rogers, CEM-1, CEM-3, Polyimide, as well as aluminum and copper for IMS circuits.

PROPCB offers a minimum track width of 3 mils and a minimum spacing of 3 mils.

Yes, we provide impedance control with a tolerance of +/- 10%, which is crucial for advanced applications such as RF and microwave circuits.

We provide a variety of finishes, including HASL, ENIG, OSP, silver immersion, hard gold, and graphite. Each has its specific characteristics, and we can help you select the most suitable one for your project.

Yes, we offer full support for custom designs, including boards with any shape and technical requirements.

The maximum PCB size is 800 x 1500 mm. For more details on dimensions and other parameters, please refer to our technical specifications.

FR4 is a standard base material used in most PCB applications, offering good mechanical and insulation properties. Rogers laminates, on the other hand, provide superior dielectric properties and signal stability, making them ideal for high-frequency applications such as RF and microwave devices.

HASL (Hot Air Solder Leveling) is a process where the PCB is coated with solder (leaded or lead-free) for protection and solderability. ENIG (Electroless Nickel Immersion Gold) is a nickel-gold coating offering better surface quality, higher corrosion resistance, and longer lifespan, especially in high-reliability applications.

The color of the solder mask impacts aesthetics and practicality. Green solder masks offer the best visibility during inspection. White solder masks are popular in LED applications for reflecting light, while black solder masks make reverse engineering and repairs more challenging.

Impedance control ensures precise signal stability, critical in RF, microwave, and high-frequency devices. We provide impedance control with a tolerance of +/- 10%, ideal for advanced telecommunications and industrial applications.

The choice depends on your application:

  • HASL is economical and suitable for most projects.
  • ENIG offers high reliability and durability.
  • Silver immersion provides excellent conductivity.
  • Hard gold is ideal for contact surfaces subjected to intense use.

Yes, we offer IMS PCBs with aluminum or copper cores, providing excellent heat dissipation. These are ideal for high-power applications like LED systems, power supplies, and automotive electronics, where efficient cooling is essential.

As the name suggests, flexible PCBs are made from bendable materials, allowing them to fit in non-standard shapes. Rigid-flex PCBs combine flexible and rigid sections, offering structural durability and mounting variation, ideal for complex applications such as medical and automotive devices.

We offer PCBs with a board thickness ranging from 0.1 mm to 10 mm, a minimum trace width of 3 mils, a minimum spacing of 3 mils, and a maximum copper thickness of 12 oz (420 µm).
