What Does PCB Assembly Mean?

What Does PCB Assembly Mean

Printed circuit board assembly, also known as PCBA, is the process of mounting various electronic components to a PCB. A circuit board prior to assembly of electronic components is known as PCB. Once electronic components are soldered, the board is called Printed Circuit Board Assembly (PCBA). The traces or conductive pathways engraved in the laminated copper sheets of PCBs are used within a non-conductive substrate in order to form the assembly. Attaching the electronic components with the printed circuit boards is the concluding action before using the fully operational electronic device.

PCB Assembly Manufacturing Design Tips

PCB Assembly Manufacturing Design Tips

  • Choosing between ROHS (LEAD-FREE) or standard (LEADED) solder

JHYPCB is able to produce both RoHS and Leaded Solder boards. In terms of rework and removing components,leaded solder is easier to deal with. It also offers a cleaner, shinier finish.

RoHS is used most frequently when shipping to Europe. As RoHS and Leaded solder temperatures are different, boards must either be completely soldered with RoHS or Lead. This includes BGAs. Non-RoHS components can withstand RoHS process. Avoid mixed process; that is, mixed solder. For example, a standard HASL bare board should not use a RoHS assembly process.

  • Water Clean

Aqueous clean process uses water soluble flux during soldering. The board is cleaned using water. This process yields shinier solder joints and an overall cleaner looking PCBA, without any flux residue.

Use No Clean Flux only if your PCBA has some parts (batteries, microphones, speakers, relays, etc...) that can be damaged if submerged in a water wash. No Clean Flux leaves flux residue on the finished PCBA; however, flux is non-corrosive and non-conductive.

If a few components are water sensitive, you may choose to have the PCBAs processed with water soluble flux without initially soldering the water sensitive components. Make sure include specific instructions to hand solder these few components after cleaning with No Clean Flux.

  • Silkscreen

If silkscreen for assembly is not provided, full assembly drawing is required. While we assemble boards without silkscreen, we will have to bypass inspection. Errors may occur.

  • Placement (X-Y) Centroid Files

If you do not send centroid files with you CAD data, we can extract them for an extra fee.

  • Shortages

Kit audit reports are given within 24 hours.

  • Fiducial

1mm circular pad on board. Ideally, three anywhere on board -- as far away from each other as possible. They should not form an isosceles triangle. For arrays, it's preferred that they are not on rails.

  • Moisture Procedure

Inspect parts indicators: whether parts are usable straightaway. If they are not, JHYPCB uses a baking procedure to remove all moisture.

  • Paste Layers

We will use customer-supplied paste layers, when present. If they are not provided, we will create them. When creating paste, JHYPCB does not require customers' approval before usage.

  • Multi-part Assembly orders

Generally, we do not allow multi-part assembly orders. For an acceptable multi-part assembly order, combine BOMs and Centroid Files, and make sure reference designations are not duplicated.

  • Substitutions

JHYPCB will notify and seek approval from customers before making substitutions for components.

PCB Assembly Cost

PCB Assembly Cost

PCB assembly cost has its standard calculation method, which includes cost of PCB manufacturing, component, SMT/DIP assembly, test and logistics. In terms of small prototype order, engineering cost will be charged. Flying probe or frame test for PCB manufacturing, stencil and regular 5% loss of components during PCB board assembly process should be also concerned. For PCB board assembly test, it depends on the test plan and duration of completing one board. 

PCB Assembly Cost = PCB manufacturing cost + PCB frame test or flying probe test fees + PCB engineering cost (only for small prototype order) + Component cost (additional 5%) + SMT assembly charges + PCB assembly test cost + Box building charges + Package cost (for special application) + Logistics cost (requested)

Things Needed for Printed Circuit Board Assembly

Following electronics parts and consumables are needed for PCB assembly

  • Printed Circuit Board
  • Electronic components
  • Soldering materials including solder wire, solder paste, solder bar, solder preforms (depending on the type of soldering to be done)
  • Soldering flux
  • Soldering equipment including soldering station, wave soldering machine, SMT equipment, inspection and testing equipment etc.

Once all of the above equipment, electronic parts and all raw materials are arranged, it is time to start the printed circuit board assembly process.

1. PCB Manufacturing

PCB design & fabrication helps you with experienced PCB design and fabrication, high accuracy, quality control. In general, your PCB prototype can be well served by us. PCB Assembly includes layout, fabrication and assembly. We also have monthly abilities of offering 35,000 square meters PCB, 80 million point SMT and introduce ICT, flying probe, AOI, X-ray, function test, burn-in test into inspection phase. We can help you with a system of transforming natural resources, raw materials and components into a finished product that is delivered to the end customer and strive to have the most optimized supply chain to make efficient and costs lower.

2. Screen Printing of Solder Paste onto PCB Board

loctite solder pastePhysicochemical and process property of solder paste directly impact SMT soldering quality. Solder paste printing is applicable for placing appropriate amount solder paste onto PCB pads, in order to ensure good circuit connection between SMT components and PCB pads and their mechanical strength. Solder paste printing is the critical process of SMT. Metal template printing is conventionally applied so far. According to related statistics, 60%~70% quality problems are caused by solder paste printing in premise of quality guarantee of components and printed circuit board. Requirements of solder paste printing:

a. Place solder paste appropriately, evenly and uniformly. Solder paste shape is clear and neighbor shapes do not connect. Solder paste shape is in compliance with that of pad, without any dislocation.

b. In general, the unit area solder paste amount should be 0.8mg/mm2, particularly 0.5mg/mm2 for narrow-pitch components.

c. After solder paste printing, the shape has no heavy collapse and edges are trim. Plate surface is not allowed to be contaminated by solder paste.

There are a large variety of solder paste with different alloy compositions, granularity and viscosity even for all from one manufacturer. How to choose appropriate solder paste highly impacts the product quality and cost. Now NOD Electronics is using Loctite lead free solder paste. We have figured out Loctite solder paste is reliable to ensure good product quality after process engineering test of its printability, demoulding, thixotropy, cohesiveness, wettability, welding spot defect and residue.

3. Lead-free PCB Assembly

In light of environmental concerns and customer request, we can offer lead-free PCB board assembly which complies with RoHS standards. At upstream, we choose PCB laminates in compliance with RoHS standards for PCB manufacturing. Also we use lead free solder paste and related reflow/wave ovens. We strictly fulfill RoHS requirements in light of your local regulations and don`t want to make you into any trouble on this basis.

4. Burning Program and In-Circuit Test (ICT)

Our test engineers will check short circuit, voltage, current, signal transmission of PCB assembly boards according to your ICT test plan. A professional report will be handed up to you if for any detected problems. For batch order, we design exclusive test frames to fast the ICT test process. We are also well sophisticated with decoding and burning program for you. Related test frame will be built to ensure products work effectively according to your requirements.
