Find some information about world class PCB services:

The PCB assembly has numerous steps which includes surface mount technology (SMT) and through hole technology. SMT is a process where the electrical components are mounted on the surface of a PCB. In the SMT PCB assembly process, the printer circuit board consists of the solder paste on the connection pads along with the components, which are then reflowed in a furnace to melt the solder paste. It then forms a connections in the electrical and mechanical components leading to PCB.

In through-hole PCB assembly process, the component leads are used onto the board and the leads are joined via Dip soldering process. A few SMT components can be used on the lower side of the board and can be joined by the wave soldering method.

Jayshree Instruments is an Ahmedabad based company offering the most authentic and adaptable PCB assembly manufacturer from India. We promise flawless and value for money production of various kinds of complicated and heavy PCB assembly from India.

PROCESS OF PRINT CIRCUIT BOARD ASSEMBLY

The PCB Assembly has a before and after process which includes certain step. Here we have described the steps of before the assembly process:

STEP 1: Solder Paste Stenciling

The primary step of PCB Assembly, Is to apply solder paste to the circuit board. The process of doing this is similar to a screen-printing a shirt, but the difference is here instead of a mask, a thin, stainless steel stencil is placed on the PCB. The step assemblers to apply solder paste to certain areas only of the would be PCB. This is the area where the components settle in the actual PCB.

If it is a professional PCBA line, a mechanical stand holds the PCB and stencil together in place. Then particular amount of solder paste is applied in the intended areas with the use of an applicator. Then the machine continues to spread the paste over the stencil by applying it on the open area, evenly. Once done with the process of this step, the stencil can be removed and the solder paste stays in the intended location.

STEP 2: Pick and Place

After the first step, the PCBA process moves on the pick and place machine where a robotic device puts surface mount components on the ready PCB. Then SMD’s check for the non-connector components on PCB’s. After this the SMD’s or the surface mount components are soldered on the surface of the circuit board in the further process.

The process can be done manually with a pair of tweezers where the assemblers has to pick and place the components manually. But now, this step is usually executed by an automatic process among the PCB manufacturers. The step moved to an automatic process as machines tend to be more precise and consistent in comparison to the manual process. Also machines can work for numerous hours without facing issues like fatigue, eyestrain etc.

STEP 3: Reflow soldering

After the solder paste and surface mount components are together and in place they need to be there, meaning the solder paste needs to solidify holding components to the board.

Through the step of “reflow”, PCB assembly can implement this process. After the step of pick and place, the PCB board is moved to the conveyer belt which moves through a reflow oven which is huge and is similar to a commercial pizza oven. The oven includes a series of heaters which heat the board up to 250 degrees Celsius or 480 degrees Fahrenheit which is hot enough to melt the solder in the solder paste. The solder starts melting and continues to move through the oven and then passes through the series of cooler heaters. This allows the melted solder to cool down and form a solid shape in a controlled way.

This process helps to create a fixed solder joint to keep the SMD’s and PCB connected. Numerous PCBA’s need special consideration during the process of reflow, especially in the case of two-sided PCB Assembly.

STEP 4: Inspection and Quality control

After the reflow process once the surface mount components are soldered in place, the board needs to be tested for its functionality. Sometimes, disturbance during the reflow process leads to poor connection quality or absolute lack of connection. Other side effects of this movement include shorts, as misplaced components can often connect portions of circuit that actually is not supposed to connect. Cross checking such errors and misalignments includes one of several different inspection methods. Some of the common inspection methods include:

– Manual checks:

Apart from the upcoming latest trends of automated and smart manufacturing, self and manual checks are still trusted in PCB Assembly process. For smaller lots, an in-person analyzing by an experienced designer is an effective method to inspect the quality of a PCB post the reflow steps. Although, this process tends to become increasingly impractical and uncertain as the figure of inspected boards increases. Looking at such nominal components for more than an hour may lead to optical fatigue which leads to less accurate inspections.

STEP 5: Through-Hole Component Insertion

As per the type of board under PCBA, the board may include different kinds of components apart from the common SMD’s. This may include plated through-hole components or plated through-hole components. PTH is a hole in the PCB which is plated through the board.

The PCB components use these holes to pass a signal from one side of the board to the other. And so in such cases, soldering paste would not be beneficial as the paste will run straight through the hole without a chance to adhere. In replacement of soldering paste, PTH components require a more specialized and advances soldering method in the further process of PCB assembly like manual soldering and wave soldering.

After the completion of this step the PCB can move forward to the final inspection or can repeat the previous steps if additional parts are to be added.

STEP 6: Final Inspection and Functional Test

Once the soldering step of PCBA process is completed, a final inspection tasks place to check the PCB’s functionality. This inspection is also known as the ‘functional test’.

In this test the PCB goes through its paces, repeating the normal circumstances where the PCB’s will operate. Power and simulated signals run through the PCB’s in this inspection. And the tester’s monitor the PCB’s electrical characteristics.
