Without a doubt, a professional manufacturer is necessary in PCB production. You should have a basic understanding of PCB manufacturing. Before selecting the one that is ideal for a given purpose, consider the various designs, types, quality, manufacturer’s competency, uses, and maintenance.
PROCESSES OF PCB MANUFACTURING
PCB fabrication can be accomplished in a variety of methods. Regardless of these differences, the core stages in PCB fabrication remain the same.
The fundamentals of PCB manufacturing
Following the selection of bare PCB boards, the following step is to design the required tracks on the board and then remove any unnecessary copper. It’s worth noting, though, that PCB manufacture is accomplished using a chemical etching process. Ferric chloride is the most common type of etch used on PCBs.
Then, using the photographic method, recreate the pattern of the original tracks. Normally, a thin layer of photo-resist is applied to the copper on bare PCBs. Then, using a photo-mask of photographic film, expose it to light. This will enable the relevant tracks to be detailed. The images created on the tracks are then transferred on to the photo-resist in this way. The photo-resist is then placed in a developer after that. The photo-resist will only be applied to the surface portions of the PCB where tracks are required.
SELECTING THE APPROPRIATE PCB MANUFACTURER
Choosing the right PCB manufacturer necessitates deliberation. However, making decisions can be more difficult and intimidating than you believe. Here are some suggestions to help you choose the proper PCB manufacturer for your project.
Check to see if the maker is certified.
IPC, UL, and ISO are some of the most prevalent certifications for PCB makers. Ideally, you should choose a manufacturer that is quality-assured and follows the 20-step high-quality PCB manufacturing process.
Understand the manufacturer’s company and job experience.
If your preferred manufacturer has a longer track record, you may rest assured that they are well-liked by their clients. PCB manufacturers, on the other hand, will be less likely to commit mistakes if they value their brand and reputation. Furthermore, they understand the importance of delivering high-quality work and services.
Find out how many clients they have on their client list.
Genuine PCB manufacturers are happy to show you their customer list, both new and old. They may even be able to show proof of how great their relationship with previous clients was and why they departed.
What distinguishes them from other manufacturers
Check to see if your preferred manufacturer stands out from the competition.
What is the estimated delivery time?
Good PCB manufacturers don’t take delivery times lightly since they understand how important consistency is to their brand. Deliveries that aren’t missed boost the level of trust that customers have in them.
Check to see if they’re manufacturers or brokers.
To find out, inquire about the PCB manufacturing methods with your manufacturer. You can relax if he provides you a thorough description of how it’s done and inspected.
In general, individuals look for good PCB makers in the following ways:
They go to their website and read customer testimonials.
They meet with manufacturers face to face and ask a few questions.
People also go over the websites of PCB manufacturers in depth to learn more about what they have to offer.
