Even in this modern age, myths and fairytales still have a place in every sector. This is of no difference when it comes to PCB assembly and manufacturing. There are several myths existing in the electronic manufacturing industry and many trust them blindly. However, following such myths thoughtlessly can trouble your assembly in a number of ways. Let’s uncover a few amongst the popularly heard myths pertaining to the PCB assembly. We will also see the explanation for such myths.
Top 6 Myths Existing in the PCB Industry
Production of defective boards and higher overall production costs would be the direct outcomes if you cling to the following myths.
Myth: Place Components Anywhere on the Board
Fact: There are several components together such as resistors, LED’s, transistors, capacitors, inductors, diodes make a PCB functional. Each of this component must be placed at specific locations as per the specifications provided to achieve a successful PCB assembly.
Myth: Via in Pad Can Damage your Assembly
Fact: In case via in pad is not assembled correctly, the myth can be true. Sometimes, it may happen that plating chemicals get trapped while making via in pad, which damages the board. Fearing this, many of the board manufacturers, especially those who are new to the field, refrain from keeping via in pad. However, be informed that via in pad imparts several advantages to the boards.
Myth: Layout for both Prototype and Actual Production is the Same
Fact: This is not true. In the case of prototype, manufacturers usually opt for through-hole for as many parts as it can limit the expense and ease the soldering process. However, when it comes to the actual production, through-hole parts get replaced with surface-mount parts.
Myth: Trace Widths Can’t Be Lesser Than 3 Mils
Fact: In the early days of PCB manufacturing, this was true. However, with the advancement of PCB assembly and semi-additive manufacturing, there won’t be any problem in using trace widths smaller than three-thousandths of an inch.
Myth: Right Power Delivery is not so Critical in Layout
Fact: To assure the production of a better performance board, the delivery of the right current is of paramount importance. Some parts require much more power compared to others in the board. This has to be taken into consideration stringently while designing the boards.
Myth: A Beautiful Design is Everything
Fact: PCB manufacturers of today’s age use EDA design tool to design the boards taking into consideration the customers’ demand. However, while designing using the EDA design tool, designers are not constrained to any boundaries, instead, they can virtually have any annular ring size, track width, spacing, among others. However, during the actual production process, this freedom in design won’t always function as expected when applied in the real world. Hence, a beautiful design is not everything. Instead, the designers should ensure the real world limitations and design boards accordingly.
Like the ones aforementioned, there are similar other misconceptions when it comes to PCB assembly and manufacturing services. Believing in those myths will only result in confusions and performance issues. However, those manufacturers like Janssen Engineering Group, usually won’t cling to such myths as they have immense practical knowledge in creating performance-driven and high-performing boards.
