BGA

The minimum diameter of BGA pad is 0.2MM (the sample limit can be 0.15MM).

Distance from BGA to tracks

The minimum BGA to line is 3MIL (the prototype limit can be 2.5MIL).

BGA distance

The minimum distance from the BGA solder pad edge to solder pads edge of other components is 0.15mm

BGA and BGA distance

The minimum distance from the center of one BGA solder pad to the center of another BGA solder padis 0.35mm.

IC programming services

Highleap Electronic offers IC programming services that enable you to subcontract the programming of integrated circuits (IC), eliminating the complexity and substantial time commitment associated with programming.

While programming can be carried out post-SMT mounting assembly, this approach is only suitable for prototype PCB assembly. In the context of high-volume PCB assembly, pre-assembly IC programming proves to be a more competitive choice. With this option, you can take advantage of cost-effective programming, rapid turnarounds, and zero defects.

Meet a variety of needs of printed circuit boards

PCB Assembly Process Flow

1

Incoming Material Inspection

The purpose of incoming material inspection is to prevent poor quality and delay delivery from defective materials. We should make sure the PCB boards are correct and the incoming components are consistent with BOM to be soldered.

2

Solder Paste Printing

It’s a key part of PCBA process. The most widely used method for applying solder paste to a PCB is through a laser stencil printer. This process precisely deposits the right amount and thickness of solder onto the solder pads.

3

Solder Paste Inspection (SPI)

SPI enables the direct assessment of solder paste quality on PCBs and offers insights into the types of defects present. Manufacturers can leverage solder paste inspection to minimize defect rates, resulting in substantial cost and time savings.

4

SMD Component Placement

In the Surface Mount Device (SMD) phase, automated machines meticulously place components on the solder paste. This step requires high precision, as even a minor misalignment can lead to faulty connections.

5

Reflow Soldering

The assembled PCB then enters the reflow soldering oven. In this controlled environment, the solder paste melts and solidifies, forming secure connections between the components and the PCB.

6

Automated Optical Inspection (AOI)

Quality control is paramount. AOI systems use cameras to examine the solder joints and components for defects. Any inconsistencies are flagged, and corrective measures are taken.

7

Repair

PCBs that do not pass AOI inspection will be forwarded to maintenance personnel for rework. Rework is carried out using tools such as soldering irons and repair workstations to rectify the identified problems.

8

Through-Hole Component Soldering

Through holes are drilled into the PCB, and components are manually or automatically inserted. These components are then soldered from the opposite side, ensuring robust connections.

9

Wave Soldering

The PCBs are conveyed over a bath of molten solder, allowing the soldering surfaces of the through holes to directly connect with the molten solder. 

10

X-Ray Inspection

X-ray inspection becomes critical if there are components such as quad flat no-leads (QFN) and ball grid arrays (BGA) on the printed circuit board. This method can uncover hidden assembly defects that may not be visible through standard visual inspection.

11

First Article Inspection

During this stage, various data such as the BOM, coordinates, designators, or sample images are inputted into the application to create a test program. 

12

IC Programming

Following PCBA production, there are multiple methods available for IC programming. Highleap ELectronic provides offline programming and online programming.

13

Functional Test

Functional test assesses the PCB’s functionality, ensuring that it meets expected electrical characteristics and performs as intended.

14

Visual Inspection

Visual inspection of the assembled board must adhere to the IPC – 610 inspection standard. This standardizes the inspection process for finished products, guaranteeing soldering quality and preventing the shipment of defective boards.

15

PCBA Cleaning

In the final production of Printed Circuit Boards, a cleaning process is essential to eliminate soldering residue like flux, dust, and solder beads from the assembled PCB. Once cleaning is complete, we can proceed to the next step of packaging.

16

PCBA Packing

Before shipping, it is imperative to employ specialized packaging for PCBA to safeguard against damage during transit and guarantee the pristine condition of the final PCBA board upon delivery to the customer.
