Best PCBA Manufacturing Equipment Services in India


PCB is a Printed Circuit Board. It's a significant electronic part, which is a help for electronic parts and a transporter for electrical associations between electronic parts. As it is created by printing the expected picture on the substrate, it is known as a "printed" circuit board. It's most usually produced utilizing copper-clad epoxy sap/glass material compound.


The PCB is frequently comprised of various layers with 4 and 6 being the most normally utilized, depending on the necessary number of sign layers.


At the point when countless PCBs must be made, odds are parts will not be physically bound manually. This is where proficient gathering houses like Seeed will step in, to assist with manufacturing both the uncovered sheets and collect every one of the parts onto the Printed Circuit Boards, or PCBs.

Yet, have you at any point thought about how your makers can stick that monstrous number of small parts onto your PCBs? I have, yet that was until I needed to drive through passages of specialized language online about the apparatus that takes care of business. While there's nothing provocative about PCBA producing, understanding how the cerebrums of all hardware are made most certainly gives pleasure and a feeling of achievement. Heaps of thought go into each phase of the gathering system to convey an entirely working board. Furthermore, with the gadgets getting increasingly progressed, the hardware used to make PCBs are steadily improving and more energizing than at any other time.

In PCB gathering, there are 4 primary phases of SMT, or Surface Mount Technology get together utilizing the reflow strategy, which are glue application, mechanized part situation, binding, and review. The essential gear expected for PCB gathering incorporates:


  • Bind Paste Printing machine

  • Bind Paste Inspection (SPI) machine

  • Stick Dispensing machine

  • Pick-and-Place machine

  • Reflow Soldering machine

  • Wave Soldering machine (for through-opening parts)

  • Programmed Optical Inspection (AOI) machine

  • In-Circuit Test (ICT) Fixture

  • Practical Validation Test (FVT) Fixture

Bind Paste Printing Machine


The initial phase in PCB gathering is the use of bind glue onto the board. Bind glue is a dim shaded goo produced using a combination of minuscule particles of metal compounds; normally of tin, lead, and silver. Consider it a paste that will keep your finished board intact. Without it, parts wouldn't adhere to your uncovered board.

Before the glue is applied, a PCB stencil is set over the board. A PCB stencil is a tempered steel sheet that has little laser-cut openings that permit patch glue to be applied exclusively to the region of the board where the parts contacts will ultimately sit on the completed PCB, for example, the SMD cushions.


During the use of patch glue, the PCB stencil and the PCB are gotten into a place in the mechanized glue printer. A wiper then, at that point, applies without lead weld glue on the cushions in exact sums. The machine then hauls a cutting edge across the stencil, to spread and store the glue equitably in the ideal regions. After the stencil is taken out, the patch glue will be precisely where we maintain that it should be (ideally).

Weld Paste Inspection (SPI) machine


Various industry studies have brought up that up to 70% of SMD binding issues are followed back to inappropriate or inadequate patch glue printing. Thus, the subsequent stage is to check to assume that the binding glue is printed appropriately onto the board. While utilizing great bind glue printing strategies are in many cases enough for PCBs in low volumes, SPI ought to be thought about while producing higher volumes of PCB to stay away from high modification costs.
