SMT Chip Processing

SMT Chip Processing Manufacturer

Chip processing using SMT (surface mount technology) is a method of producing electronic components and circuit boards. It entails using a pick-and-place machine to place small surface mount devices (SMDs) onto a printed circuit board (PCB). SMDs are typically made of a metal and plastic blend, and they have tiny leads or pads that are soldered to the PCB.


Committed to Manufacturing Solutions

Surface mount technology (SMT) is an assembly and production method that applies electronic components directly onto the surface of a printed circuit board (PCB). This process allows for automated production to complete more of the required assembly to create a working board.

Testing Procedures

The pick-and-place machine takes SMDs from a reel or tray with a vacuum nozzle and places them on the PCB according to a set of instructions known as a pick-and-place file. A small amount of adhesive or their weight holds the SMDs in place on the PCB.

Following the placement of the SMDs on the PCB, the board is typically reflow soldered, which involves heating the board to a high temperature to melt the solder and create a permanent connection between the SMDs and the PCB. The board is then cooled, and any excess solder is removed using a technique known as solder paste cleaning.

SMT Chip Processing asked questions

What is SMT chip processing?

How is SMT chip processing different from through-hole technology?

What are the advantages of SMT chip processing?

What are the challenges of SMT chip processing?

What equipment is used in SMT chip processing?

What is the process of SMT chip processing?

Preparation: The PCB is cleaned and prepared for the soldering process.

Printing: Solder paste is applied to the PCB using a solder paste stencil.

Placement: The pick and place machine places the components onto the PCB in the correct positions.

Reflow: The PCB and components are placed in a reflow oven, where they are heated to a high temperature, melting the solder and causing it to flow around the components.

Inspection: The completed PCB is inspected to ensure that all components are correctly placed and soldered.

What are some common defects in SMT chip processing

Michaela ★★★★★

The assembled PCBs that were delivered worked flawlessly. The component placement is excellent. Mis wang, the WINOW engineer in charge of our project, and I hit it off right away. She asked pertinent questions to ensure that the project was properly completed. We had a very nice, short, and to-the-point conversation.

Herbert ★★★★★

This board is required to charge my robotic platform's lipo batteries (rover). First-time order with excellent communication throughout the ordering process, manufacturing progress, and tracking up to delivery. Very good price, especially for the first order with a credit for a discount.

Al Lemke ★★★★★

The boards arrived yesterday, and assembly has begun. Excellent solder wetting, clean line definition, and drill holes that are precisely in the center of the via lands.
Please convey my gratitude to everyone who created such wonderful boards.
