New BGA Solder Mask Repair Technique Using Laser Cut Stencils

Technical Library | 2007-02-01 10:08:40.0

The increased replacement of high lead count SMT devices with BGAs and other high ball count area array packages has brought increased challenges to PCB rework and repair. Often solder mask areas surrounding BGA pad areas are damaged when components are removed.

2020 AUTONOMOUS VEHICLE TECHNOLOGY REPORT

Technical Library | 2021-02-11 03:07:39.0

Motorized transportation has changed the way we live. Autonomous vehicles are about to do so once more. This evolution of our transport - from horses and carriages, to cars, to driverless vehicles, - has been driven by both technical innovation and socioeconomic factors. In this report we focus on the technological aspect.

Boundary Scan Skews Test Coverage Tradeoffs in your Favor

Technical Library | 2007-08-23 14:30:03.0

The complexity and programmability of modern embedded boards means that knowledge built up during debugging and testing must be regarded as Intellectual Property (IP) and therefore preserved. But many of the processes and tools used today do not provide a means to preserve or pass on this IP, and thereby forego valuable opportunities to save time and improve quality during subsequent stages of product development.

Be Vigilant: It’s a Jungle Out There

Technical Library | 2013-04-12 07:22:40.0

Here Chris talks about the pitfalls, the paucity of safe options for manufacturers seeking rare components, and his exasperation with organisations that appear to shelve common sense at the first sign of a shortage. He shares his ‘no nonsense’ approach to getting things right first time, and explains his thinking in establishing an independent distributor focused exclusively on delivering 100% component integrity.

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.

Mixed Metals Impact on Reliability

Technical Library | 2013-12-19 16:57:50.0

With the adoption of RoHS and implementation of Lead Free solders a major concern is how this will impact reliability. Both commercial and military hardware are impacted by this change even though military hardware is considered exempt from the requirements of RoHS. As the supply chain has moved to the new lead free alloys both markets are being forced to understand these impacts and form risk mitigation strategies to deal with the change. This paper documents the effect of mixing Leaded and Lead Free alloys on BGA devices and how this impacts reliability. Three of the most common pitch BGA packages are included in the study to determine if the risk is the same as pitches decrease
