In this episode, Michael Charlesworth, Engineering Manager for Cogent
Technology, brings an insight into PCB Layout Best Practice and how you
can incorporate this in to your designs with the benefit of delivering
an improved 1st time pass rate though AOI, reducing the need for
rework, which in turn equates to lower manufacturing costs.
Specialized circuit card assembly service provided by circuit card makers
Advantages of qualified circuit card assembly
If you’re considering doing the circuit card assembly in-house at a professional level you’re shortly going to see the initial investment expense is extremely high. You need at the least: one pick and place machine, one stencil printing machine and one reflow oven. It is likely you likewise want other relevant gear for examination work and hand soldering gear. You will need labor force and expertise that could increase the investment cost a lot. And finally when you take into account there is very little ROI from this sort of financial commitment you will definitely promptly prefer to contract out the circuit card assembly service. Generally speaking assigning the circuit card assembly work to an outward service provider ought to be more economical.
Then there is the facet of quality; a provider dedicated to circuit card assembly services will have the practical knowledge and staff members to make available high quality. They will also invest in their development by always having the most advanced technology making sure that the buyer gets all the advantages from the latest assembly technologies. You may find that you’ll hit a equipment related limit doing in-house assembly if you fail to up-grade the equipment regularly, e. g., you might end-up in a scenario in which you aren’t able to easily assembly the new BGA package for a fresh processor.
Additionally there is the aspect of quality control. A great circuit card assembly plant may also have an excellent established quality control service you may possibly take advantage of by not having to do the quality control in-house. Undoubtedly, you may need to do extra quality control step in-house but it is good to know at least the pcb’s are all running efficiently when they get away from the assembly line.
The negative stuff of pro circuit card assembly
A good reason you will not want to contract out the assembly of your project is to take care of IP. In the event you are working away at some secret project or the newest idea that will reinvent something, you should keep that as discreet as possible so in that case you could possibly do the circuit card assembly on-site.
In addition there are cases when the turn-around time of a prototype is vital so you might not afford to wait one week for your circuit card to return from a pro assembly line. Therefore it may make more sense to accomplish the assembly in house.
Expenditure is also an important reason you possibly will not plan to decide on a professional circuit card assembly plant, especially for smaller businesses or fans. Prices for circuit card assembly services have diminished a lot in the past couple of years hence this is less of an issue presently but nonetheless you do not see a large amount of individuals sending their one off hobby projects to a circuit card assembly plant.
