Laser Direct Imaging of Tracks on PCB Covered With Laser Photoresist

Technical Library | 2008-04-15 14:43:08.0

The increasing demands for miniaturization and better functionality of electronic components and devices have a significant effect on the requirements facing the printed circuit board (PCB) industry. PCB manufactures are driving for producing high density interconnect (HDI) boards at significantly reduced cost and reduced implementation time. The interconnection complexity of the PCB is still growing and today calls for 50/50 μm or 25/25 μm technology are real. Existing technologies are unable to offer acceptable solution. Recently the Laser Direct Imaging (LDI) technology is considered as an answer for these challenges.

Printed Circuit Board Assembly & Choosing a Vendor

Technical Library | 2019-10-24 06:29:59.0

Making your novel electronic item design ready for mass fabrication and printed circuit board assembly consists of a lot of steps as well as risks. I will provide a few recommendations about how to neglect pricey errors and how to reduce the time to promote your novel item designs. You can hire printed circuit board assembly services for this. As soon as you have accomplished your product as well as printed circuit board design, you wish to get started developing prototypes prior to you commit to big fabrication volume. A lot of design software packages, for instance, PCB layout design software, as well as an industrial design software program, possess simulation potentials incorporated. Carrying out a simulation facilitates curtailing numerous design mistakes prior to the first prototype is developed. In case you are developing an intrusive item, you might desire to think about a modular design wherein all of the chief functionalities are situated in individual modules. All through your testing, you could then swap modules that don’t cater to the design limits. Spinning individual modules would be swifter and more cost-effective in comparison to spinning a complete design. Counting on the design intricacy, you can mull over manually mounting printed circuit board elements to bank dollars. Nonetheless, for medium to big intricacy this procedure likely to be very time taking, typically in case you wish to create numerous prototypes. Hence it makes sense thinking about a contract manufacturer for the assembly. Whilst running miniature quantity fabrication runs, the fabrication setup expenditure will usually control the by and large prototype constructs expenditure. Whilst seeking a subcontractor, it is finest to choose a vendor that focuses on prototype builds to reduce the cost. Prototype printed circuit board fabricators characteristically join the circuit boards of a number of clients which efficiently shares the setup expenditure in the midst of some customers. The disadvantage is that you would characteristically only be able to want among numerous standard printed circuit board material thicknesses as well as sizes. Apart from choosing a supplier with low setup expenditure, choosing a firm that would moreover be capable to manage your whole fabrication runs curtails mistakes because switching fabricators have the chance of errors owing to a specific supplier interpreting fabrication design data in a different way. This manner your design is already translated into the particular machine data that implies little or no setup expenditure for your final fabrication. A few PCB manufacturers also provide printed circuit board design services that are awesome plus if you do not possess experience with the design. Moreover, these vendors would be capable to help you in case there are issues with your design folders and be capable to detect issues prior to the fabrication.

Investigation of Cutting Quality and Mitigation Methods for Laser Depaneling of Printed Circuit Boards

Technical Library | 2019-09-11 23:33:04.0

There are numerous techniques to singulate printed circuit boards after assembly including break-out, routing, wheel cutting and now laser cutting. Lasers have several desirable advantages such as very narrow kerf widths as well as virtually no dust, no mechanical stress, visual pattern recognition and fast set-up changes. The very narrow kerf width resulting from laser ablation and the very tight tolerance of the cutting path placement allows for more usable space on the panel. However, the energy used in the laser cutting process can also create unwanted products on the cut walls as a result of the direct laser ablation. The question raised often is: What are these products, and how far can the creation of such products be mitigated through variation of the laser cutting process, laser parameters and material handling? This paper discusses the type and quantity of the products found on sidewalls of laser depaneled circuit boards and it quantifies the results through measurements of breakdown voltage, as well as electrical impedance. Further this paper discusses mitigation strategies to prevent or limit the amount of change in surface quality as a result of the laser cutting process. Depending on the final application of the circuit board it may prompt a need for proper specification of the expected results in terms of cut surface quality. This in turn will impact the placement of runs and components during layout. It will assist designers and engineers in defining these parameters sufficiently in order to have a predictable quality of the circuit boards after depaneling.

The Effects of PCB Fabrication on High-Frequency Electrical Performance

Technical Library | 2016-07-21 18:16:06.0

Achieving optimum high-frequency printed-circuit-board (PCB) performance is not simply a matter of specifying the best possible PCB material, but can be significantly impacted by PCB fabrication practices. In addition to appropriate circuit materials and circuit design configurations to meet target performance goals, a number of PCB material-related issues can affect final performance, including the use of soldermask, the PCB copper plating thickness, the conductor trapezoidal effect, and plating finish; understanding the effects of these material issues can help when fabricating high-frequency circuits for the best possible electrical performance.

Avoidance of Ceramic-Substrate-Based LED Chip Cracking Induced by PCB Bending or Flexing

Technical Library | 2022-09-25 20:18:33.0

Printed circuit board (PCB) bending and/or flexing is an unavoidable phenomenon that is known to exist and is easily encountered during electronic board assembly processes. PCB bending and/or flexing is the fundamental source of tensile stress induced on the electronic components on the board assembly. For more brittle components, like ceramic-based electronic components, micro-cracks can be induced, which can eventually lead to a fatal failure of the components. For this reason, many standards organizations throughout the world specify the methods under which electronic board assemblies must be tested to ensure their robustness, sometimes as a pre-condition to more rigorous environmental tests such as thermal cycling or thermal shock.
