I agree with previous postings regarding print speed: Solder paste type/versus fine pitch. Question: Is this a double sided pcb with fairly easy component packages on both sides? In such case, consider make the panel like this: Every second pcb in

Very often, customers ask details about what kind of testing do we use? How do we charge it? Do I have to pay every time or only for the first time? Is this testing safer and better than other one? etc In this blog, let's discuss the various kind of testing and their advantages and disadvantages. Some of them are mandatory, some of them are optional; Some of them are fast, some are slow; some of them are more reliable, and some not. Hope you will have a better understanding about various kinds testing and make better decision on your next PCB order.

The PCB industry is ever changing and adapting to new technologies. OEM specifications and requirements have also advanced due to these technologies. In some cases the OEMs are asking for a low resistance test to be performed on some or all electrical test nets of the PCB or on the holes of the PCB. This requirement is typically not well defined on the fabrication drawing and that leads to misleading conclusions by the fabrication house (...) This paper will use the data gathered by the company’s operations to outline what a 4-wire Kelvin test is and how it can be used. Several examples will be illustrated of what the 4 wire Kelvin test can and cannot do. A clear definition of what limitations are present during the testing operation will be defined. The paper will assist designers in understanding how the low resistance test can assist them and also identify causes that can identify unwanted concerns/issues.
