RF design is inherently more complex than any other type of design. This is because of the unique issues that must be addressed due to the extremely high frequencies of operation for these applications.  For example, there are inherent challenges with power control, grounding structures, printed wiring board (PWB) stack-ups, laminate and surface finish selection, characteristic impedance control, signal path configurations, connectorization, pad geometries, solder mask, conformal coating, surface parasitics, exposure to harsh environments, fabrication effects, via sizing, component selection, and manufacturing process impacts.  These numerous issues must be well understood by your CM or the potential for failure is magnified.  [Read More](https://info.zentech.com/blog/how-manufacturing-processes-can-impact-reliability-in-rf-circuits) 0 Comments [Click here to read/write comments](https://info.zentech.com/blog/how-manufacturing-processes-can-impact-reliability-in-rf-circuits#comments-listing) Topics: [electronics manufacturing](https://info.zentech.com/blog/topic/electronics-manufacturing), [PCB](https://info.zentech.com/blog/topic/pcb), [PCB assembly technology](https://info.zentech.com/blog/topic/pcb-assembly-technology), [manufacturing](https://info.zentech.com/blog/topic/manufacturing), [PCB process](https://info.zentech.com/blog/topic/pcb-process), [electronics manufacture](https://info.zentech.com/blog/topic/electronics-manufacture) ## [PC Board Assembly: All About Perfect Tolerances](https://info.zentech.com/blog/bid/259388/PC-Board-Assembly-All-About-Perfect-Tolerances) Posted by [Laura Austin](https://info.zentech.com/blog/author/laura-austin) on Sat, Mar 23, 2013 @ 07:00 AM - [Tweet](https://twitter.com/share) [![](https://info.zentech.com/hs-fs/file-18549490-jpg/images/pcb_assembly12.jpg) ](https://info.zentech.com/blog/bid/259388/PC-Board-Assembly-All-About-Perfect-Tolerances) Without the help of rigorous testing and assembly compliances, the whole process of [PC Board assembly](https://info.zentech.com/blog/bid/203702/Improving-Quality-of-PCB-Assembly-Through-Solder-Ability-Testing) wouldn't be able to endure the life [cycle of being a PCB](http://www.bittele.com/Prototype-PCB-Assembly.asp) and more than likely would fail much sooner than later. All of those tests aren't just for the sake of testing, they are implemented to make sure that everything is in working order and the board itself can withstand extreme heat, cold, and even weight distribution and tolerances. However, the tests themselves even need to have perfect ratings--especially when it comes to tolerances, in particular.Tolerances are what the PCB will go through in order to pass all of its testing, making sure it can work properly in certain situations without short circuiting, breaking, or shutting down completely. But most importantly, there are also tolerances during the design phase to make sure that the board is "balanced" when it comes to all of its components and won't suffer from breakage or overload.
