PCB & PCBA, what is it?

Simply put, PCBA is the process for manufacturing a completed electronic printed circuit board (PCB) with all the necessary electronic components on it, in order for it to function as it was designed for its application.  The acronym PCBA literally means: Printed Circuit Board Assembly and it is Sunnytech's core business.

Deciding on the right PCBA provider

Not all PCBA providers are equal for obvious reasons some key features to consider are:

*Location
*Certifications
*Equipment
*Quality
*On-Time-Delivery
*Cost

Do you require local or off shore production?  Is certifications a top priority more so than equipment?  All these can and should be asked in order for you to find the best PCBA provider for your needs. 

PCB DESIGN FROM START TO FINISH

BY JOHN BURKHERT

In this Series total of 16 sections, is a step-by-step guide on printed circuit board design with information suitable for beginners to graduate-level users.

PCB Design is at the crossroads of mechanical and electrical domains. One day, you’re working with geometric dimensioning and tolerancing, and the next day you’re calculating temperature rise on a power plane. In between these two camps, there is a raft of technology that is particular to printed circuit boards.

Just as the clothing industry weaves cotton or synthetic materials in different ways, so too does the PCB industry. The nature of the resin and method of the weave are broken out into what is called slash sheets by the IPC. (1) They have two main documents that are relevant to rigid stack-up materials; IPC-4101 for typical materials and IPC-4103 for high speed/high-frequency materials. Flexible materials are catalogued in IPC-4102 and high density interconnect materials are covered by IPC-4104.

A PCB is only as good as the sum of its parts. Components are categorized in various ways. One way is to identify parts as either passive or active. Passive parts are the basic building blocks, resistors, capacitors, and inductors are examples. Quite often, they have two pins but they can also be packaged with several individual circuits in a single package. Resistor packs are the most common passive components to be gathered into groups.
