Printed Circuit Board Assembly Process, Technology, Tips

Printed Circuit Board Assembly Process, Technology, Tips


Printed circuit board assemblage, also called PCBA, is the process of soldering or assemblage of electronic elements to a circuit board. A circuit board ahead of assembly of electronic parts is termed a PCB board. As soon as electronic parts are soldered, the board is named Printed Circuit Assembly (PCA) or Printed Circuit Board Assy (PCBA).

It must be mentioned that assemblage of a circuit board is not the same as making a circuit board. Manufacturing printed circuit boards engage several steps such as PCB board designing and making PCB prototype. Once a circuit board is prepared, electronic parts ought to be soldered upon it before being utilized in any electronic devices. This assemblage of electronic parts relies upon sort of circuit board, sort of electronic parts and moreover usage the circuit board.

Things Deparately Needed for Printed Circuit Board Assemblage

The Following electronic components and elements are necessary for PCB board assy

Electronic parts
Soldering materials which include solder wire, solder paste, solder bar, solder preforms (depending on the kind of soldering to be completed)
Soldering flux
Soldering gear such as soldering station, wave soldering device, SMT gear, inspection and testing machines etc.

Right After all the above equipment, electronic parts and all of materials are set in place, it is time to start up the process of assembly .

PCB Assembly with Thru-Hole Electronic Components

PCB Assembly

Electronic parts which have leads popping out and are positioned through tiny holes in the PCB board for soldering are known as through-hole electronic components. The assembly or soldering operation for these types of elements incorporate wave soldering and hand-operated soldering – Wave Soldering – A PCB board assemblage process in which solder in the sort of solder bar are put in a high-temp bath. This solder stays in the bath in molten form and forms a wave at very high temperature. The range of temperature will depend on the kind of solder. Conventional tin / lead (Sn/Pb) solder has lower melting point than lead-free (Pb-Free) solder. The circuit board along with the thru-hole electronic components in holes is passed over molted solder by using a conveyor strap. The complete wave soldering process consists of the below steps:

Putting in electronic components
Flux use

As soon as the wave soldering is finished, the PCBA is cleaned out and tested. If any error or solder joint is discovered, it’ll be returned for change, which is usually achieved by hand. Hand-operated Soldering – Hand-operated soldering is complete in fabricating units with less work or in rework / fix work. A superior quality soldering station, soldering iron and solder wire and flux are utilized along the process.

Surface Mount Technology (SMT) Suitable for SMD Parts

Surface Mount Technology or SMT is a PCB assemblage course of action for SMD (Surface Mount Device) parts. SMD elements don?¡¥t have leads and legs. They can be mounted on the surface of the circuit board. The machines, parts as well as other soldering materials consumed in this assemblage process is totally different from thru-hole soldering operation.

The software tool even delivers a 3D visualization of the circuit board without any limits on the shape and size of the PC board. The PCB board layout attribute makes it possible for up to 64 layers, and is suitable for standard output file famats for example, Gerber 274X and 274D, DXF, 3D DXF, 3D IGES and even IPC-D-356A Netlist for quick design output and affirmation.

The Mouser community provides the engineer with instructions, downloads, set of training videos and subscriber online forums.

Rigid-flex Electronic Circuit Board Design Eliminates Wearable Medical System Complications

Rigid-flex Electronic Circuit Board Design Eliminates Wearable Medical System Complications


The vast majority of printed circuit boards in the world today are simply rigid plates for connecting circuitry. However, that’s changing rapidly; the requirement for flex electronic circuit boards (or flex circuits) is aggressively increasing largely thanks to the booming wearable product industry. Probably the most significant segment of that market is the medical industry where wearable products will be utilized to collect all varieties of biological records for examination and study, as well as individual health use. Actually wearables are offered to keep tabs on heart rhythm, blood pressure levels, glucose, ECG, muscle movement, and a lot more.

The wearable devices bring many troubles for PC board designers that rigid boards don’t. The following are some of such problems along with what designers can do to help remedy them.

3 Dimensional Design

While each PC board is certainly 3 dimensional, flex circuits allow the entire assembly to be bent and folded to adapt to the package that the merchandise uses up. The flexible circuitry is collapsed to ensure that the rigid PC boards easily fit into the product package, occupying minimum space.
There is a lot more to the design, so the added challenges, than simply connecting the rigid boards. Bends have to be properly designed so boards get in line where they are meant to mount, while not placing stress on the connection points. Up to recently, engineers actually used “paper doll” models to emulate the circuit board assembly. At this point, design tools are offered that offer 3D modelling of the rigid-flex assy, helping more rapidly design and a lot greater precision.

Little Items and Squeezed Circuitry

Obviously, wearable products are required to be tiny and inconspicuous. Previously, a healthcare “wearable” maybe a Holter pulse rate monitor integrated a fairly large exterior device with a neck strap or maybe belt mount. The recent wearables are small and attach straight to the sufferer without any or very few external cables. They collect many different data and are able to even process several analyses.

An highly discreet device affixing straight to the patient dictates flex circuitry and really compressed layouts. Moreover, the board shapes usually are spherical or even more unusual shapes, requiring clever placement and routing. For this sort of tiny and dense boards, a PC board tool that is designed for rigid-flex designs helps to make handling unusual shapes easier.

Stackup Design is vital

The stackup – the map of the electronic circuit board layers – is critical when you use rigid-flex techniques. Perfectly, your PCB design software has the ability to design your stackup including both the rigid and flex parts of the assembly. As said before, the layout of the folding area ought to be built to decrease the stresses on the traces and pads.
One of the primary challenges with rigid-flex designs is qualifying multiple producers. After the design is fully gone, all aspects of the design is required to be communicated to the board fabricator so it will be effectively produced. But, the best practice is to pick one or more makers at the start of the design and work together with them to assure your design satisfies their manufacturing needs as the design moves on. Taking part with manufacturers is made simple by employing standards. In cases like this, IPC-2223 is the vehicle for getting in touch with your fabricators.

As soon as the design is done, the data package has to be assembled to hand-off to be produced. Though Gerber remains employed for standard PCBs in some companies, in terms of the difficulties of rigid-flex, it is strongly advised by both PCB program vendors together with fabricators that a more intelligent data exchange format be utilized. The 2 most wellwell-known intelligent formats are ODG++ (version 7 or higner) as well as IPC-2581, as both versions precisely define layer standards.
