    The list of PCB designers worldwide- Part 3

    Very often, our clients ask us to provide PCB design/layout service, or introduce them qualified PCB design professionals for their projects. Thus, we are making the list of PCB Designers Worldwide.
    We will put this data on our website and many other public related websites, so that people in need might contact PCB designers directly.
    The information will not be used for commercial purpose.
    If you are also PCB designer and want us to include you to the list, please email to baggio@jaapson-pcb.com
    If you have sent your details but not yet be listed on the paper, it is either because you did not provide enough details, or because it takes longer time, please feel free to ask.

  • Press-Fit Technology for Automotive Application

    Press-Fit Technology for Automotive Application

    The basic principle of a press-fit connection is that a contact terminal is pressed into a printed circuit board (PCB). There are two types of press-fit pins – the solid pin with a solid press-in zone and the compliant pin with an elastic press-in zone. In this article, we’ll discuss the elastic press-in zone.

    Press-fit technology is widely applied in multiple automotive applications. Basically, there are two options to consider – press-fit contact terminals (for single-pin insertion) and connector modules (for mass termination). The press-fit terminals for single-pin insertion usually are supplied in a reeled condition that allows the customers to apply the contacts to the PCBs in a “free” and highly flexible manner. Connector modules commonly feature customized housing components equipped with contacts (and other sub-components) in a potentially modular way according to the specific customer needs.

  • Wire Bonding Guidelines

    Wire Bonding Guidelines

    There are two wire bonding processes that are used, Thermosonic (T/S) Gold Ball Wire Bonding and Ultrasonic (U/S) Aluminum Wedge Wire Bonding. Approximately 90% of all IC Assembly in Semiconductor Packages is manufactured using Gold Ball Bonding process, while Aluminum Wedge Bonding is used to produce about 10% of other Wire Bonding requirements on Printed Circuit Boards (PCB), Printed Circuit Flex (PCF) and other Packages.

  • What are the advantages of HDI PCB technology?

    What are the advantages of HDI PCB technology?

    HDI is the abbreviation for High Density Interconnector. HDI PCB is defined as a PCB with a higher wiring density per unit area than conventional PCB. They have finer lines and spaces, smaller vias and capture pads and higher connection pad density than employed in conventional PCB technology. HDI PCB is used to reduce size and weight, as well as to enhance electrical performance of the device. HDI PCB is made through Microvia and buried vias and sequential lamination with insulation materials and conductor wiring for higher density of routing. HDI PCB is the best alternative to high layer-countand expensive standard laminate or sequentially laminated boards.

  • How to sell PCBs to Celebrities?

    How to sell PCBs to Celebrities?

    What? Sell PCBs to Celebrities? No way!
    Sorry, I used a tactic to draw your attention, and you are right, I don't have a way to sell PCBs to celebrity and they dont need them either.

    Dealing with electronics and PCB manufacturing is kind of boring sometimes, but there are always ways to make it more interesting and fun. Recently, Jaapson team tried to combine PCBs with different cartoon images, like Donald Trump, Bruce Lee, Marilyn Monroe, etc to make it more vivid. We have received many positive feedback, and would like to share them with more people.

    This is the third part of our designs, and it is still continuing...
