Top 6 Common Printed Circuit Board Problems, Common PCB Issues That a PCB Stencil Manufacturer Solves  

Common Printed Circuit Board Problems

For a terrific electronic to work perfectly, it needs an excellent Common Printed Circuit Board Problems. And for an “excellent” component to work error-free, it needs supreme quality substance as the raw materials. “Well,” the case with laptops, tablets, smartphones, and other similar devices is very much the same.

Unless and until its heart, i.e., printed circuit boards, won’t function properly. It is less likely that users will not experience a malfunction. And for such PCBs to operate smoothly, it is necessary that “they” get developed by assembling high-quality SMDs. But do you know that there is one more thing that determines the quality of (PCB) printed circuit boards?

We must tell you that “it is” how well you have applied the solder paste on the bare boards. Now we are sure you might be considering asking. But how can we ensure the successful application of solder paste on the bare boards?” Well, that’s where a PCB Stencil Manufacturer comes in. 

We know you would be pondering about the role of PCB Stencil Manufacturer in solder paste deposition, “so” we will explain that straight away. Let’s see:

What does a PCB Stencil Manufacturer do for correct PCB assembly?

Just to let you know, the famous PCB (Printed Circuit Board) stencil makers produce thin metal sheets with multiple laser-cut openings to ensure the solder paste gets applied to the bare circuit boards “very” precisely. Thus, by using such metal plates during the printing process, the operators or engineers can ensure the smooth application of solder paste over the board and leave no possibilities for solder bridging. Because if such issues occur then other defects might upsurge. That we don’t think any accountable electronics manufacturer would want.

Hence, the reputed PCB Stencil Manufacturer plays a crucial role in enabling you to print the circuit boards. “extremely” accurately, so you find it easier to fix the surface-mount devices over it. 

So, now that you know the importance of using stencils during PCB assembly. it’s time to look at the definition of this industrial material:

What is SMT or PCB Stencil?

First, you must know that SMT stands for Surface Mount Technology which is used during PCB production to assemble Surface Mount Devices on the printed circuit boards. And as far as PCB stencil is concerned, you know well it is a laser-cut steel sheet with several openings to apply solder paste on the Common Printed Circuit Board Problems. This way, you can readily print the bare circuit boards by putting the solder paste through given holes.

And once you have done this, your board is ready to move to the next stage, including:

  1. SMD placement 
  2. Reflow soldering 
  3. Automated Optical Inspection 
  4. Through-hole Assembly
  5. Wave Soldering 

Common PCB IssuesSince SMD devices are “tiny” in size, it is no easy “feat” to fix them on circuit boards correctly. Still, if you approach this task with great attention. And concentration, you can assemble the small electronic parts on the circuit boards. With high accuracy. Keep in mind, it is necessary to perform this task with a lot of care, and that’s where the work carried out by well-designed SMT stencils will reflect.


It means when the solder paste deposition on the board occurs uniformly, it will be easy to place the micro components on the PCB board without any hassle. 

In “case” you are considering buying an SMT stencil now, you must know that it gets designed as per the layout of your circuit board. So, you must provide the PCB design-related file to your potential vendor during the order placement so they can create your stencil based on that. Once you have received your desired metal sheet, all you need to do is pour the solder paste on the bare board through the given PCB stencil and leave it for drying. After it gets dried, you can proceed ahead with other processes, like the component placement. 

6 Common problems of PCB assembly that a PCB Stencil Manufacturer Solves  

  1. No short circuits 

When depositing the solder paste on the bare boards without a stencil, the chances are high that two solder points may come in contact with each other due to the irregular paste shape, resulting in causing short circuits in the future. Fortunately, a well-designed stencil is available to eliminate that issue like a breeze. 

  1. No soldering gaps 

During the manual solder paste application, you might leave some solder gaps unknowingly, translating into poor quality PCB printing. But when you have a good-quality SMT stencil at your disposal, such issues can get easily eliminated. 

  1. No inconsistent aperture 

If you use the PCB printing sheets that don’t have the same-size holes, you might get an uneven-looking board after printing. But when you call on tried and tested stencils for PCB printing, you can rest assured about the consistent aperture. 

  1. Smooth pad walls 

Replacing manual board printing with SMT stencil has several advantages, including the possibility-elimination of rough pad walls. 

  1. Accurate pad position

With a well-built PCB stencil at your hand, you can also stay “assured” of correct pad positioning, so there is no room for any possible error. 

  1. High printing accuracy 

Last but not least, PCB metal sheets allow you to print boards exactly how you see in the software or your screen, leading to the highest possible accuracy in the job.
