How to Choose the Right PCB Coating Machine Line Selecting the ideal equipment for your PCB coating line can be a complex task. In this article, we will guide you through the critical components of a standard PCB coating machine line and their solutions to common challenges. We'll delve into the line's composition, including the elevator, transfer station, coating machine, inspection station, curing oven, and their interconnectedness through a return conveyor. Let's explore each element and understand its role. Components of a PCB Coating Machine Line: Elevator: The PCB coating process starts with an elevator, efficiently transporting PCB boards to the next stage. Transfer Station: After the elevator, boards are conveyed to a transfer station, preparing them for the coating process. Coating Machine: The heart of the PCB coating line is the coating machine. We offer a range of coating machines, including I.C.T-T550, I.C.T-T550U, I.C.T-T600, and I.C.T-T650. Inspection Conveyor: Following the coating process, the boards move to an inspection station. The second transfer station is equipped with LED lights and a blue glass cover, enabling operators to closely inspect the coating quality. This feature is vital for ensuring consistent, dust-free coatings. Curing Oven: For UV-curable adhesives, we provide a UV curing oven to effectively solidify the adhesive. Return Conveyor: Beneath the entire line runs a return conveyor, connected to the elevator. This conveyor system efficiently returns PCBs from the last elevator to the first one, reducing manual handling and streamlining operations. The Advantages of the PCB Coating Line Design: 1. Easy Accessibility: The operator's station is strategically located beside the coating machine, ensuring easy access for setup and adjustments. 2. Enhanced Efficiency: The integrated return conveyor eliminates the need for manual transport, optimizing workflow. 3. Quality Control: The inspection station with the blue glass cover enables operators to inspect coatings for quality and cleanliness. 4. Dust Prevention: The blue glass cover also serves as a barrier to prevent dust contamination on freshly coated PCBs. Selecting the right PCB coating machine line is essential for achieving quality and efficiency in your operations.

Solder ball height inspection is essential to the detection of potential connectivity issues in semi-conductor units. Current ball height inspection tools such as laser profiling, fringe projection and confocal microscopy are expensive, require complicated setup and are slow, which makes them difficult to use in a real-time manufacturing setting. Therefore, a reliable, in-line ball height measurement method is needed for inspecting units undergoing assembly. (...) In this paper, an automatic, stereo vision based, in-line ball height inspection method is presented. The proposed method includes an imaging setup together with a computer vision algorithm for reliable, in-line ball height measurement.

In a typical mechatronic manufacturing functional test setup, actual load simulations are usually done by connecting the DUT outputs to power or ground in order to establish either a high or low side driver. Each output is connected with different load and the test will either be sequential or concurrent. At lower power levels, these can usually be managed with general purpose switches. However, when it comes to higher power levels of currents more than 5 amps, such switching and loading might pose a greater challenge. Furthermore, critically in the manufacturing line, the tradeoff between cost and test time would have a great influence on the test strategy.This paper will present some key points to design a cost effective high power switching and load management solution.

Package on Packages (PoP) find use in applications that require high performance with increased memory density. One of the greatest benefits of PoP technology is the elimination of the expensive and challenging task of routing high-speed memory lines from under the processor chip out to memory chip in separate packages. Instead, the memory sits on top of the processor and the connections are automatically made during assembly. For this reason PoP technology has gained wide acceptance in cell phones and other mobile applications. PoP technology can be assembled using one-pass and two-pass assembly processes. In the one-pass technique the processor is first mounted to the board, the memory is mounted to the processor and the finished board is then run through the reflow oven in a single pass. The two-pass technique has an intermediate step in which the memory is first mounted onto the processor.

Ceramics packages are being used in the electronics industry to operate the devices in harsh environments. In this paper we report a study on acoustic imaging technology for nondestructively inspecting underfill layers connecting organic interposers sandwiched between two ceramics substrates.First, we inspected the samples with transmission mode of scanning acoustic tomography (SAT) system, an inspection routine usually employed in assembly lines because of its simpler interpretation criteria: flawed region blocks the acoustic wave and appears darker. In this multilayer sample, this approach does not offer the crucial information at which layer of underfill has flaws. To resolve this issue, we use C-Mode Scanning in reflection mode to image layer by layer utilizing ultrasound frequencies from 15MHz to 120MHz. Although the sample is thick and contains at least 5 internal material interfaces, we are able to identify defective underfill layer interfaces.

In this era of electronics miniaturization, high yield and low-cost integrated circuit (IC) substrates play a crucial role by providing a reliable method of high density interconnection of chip to board. In order to maximize substrate real-estate, the distance between Cu traces also known as line and space (L/S) should be minimized. Typical PCB technology consists of L/S larger than 40 µ whereas more advanced wafer level technology currently sits at or around 2 µm L/S. In the past decade, the chip size has decreased significantly along with the L/S on the substrate. The decreasing chip scales and smaller L/S distances has created unique challenges for both printed circuit board (PCB) industry and the semiconductor industry. Fan-out panel-level packaging (FOPLP) is a new manufacturing technology that seeks to bring the PCB world and IC/semiconductor world even closer. While FOPLP is still an emerging technology, the amount of high-volume production in this market space provide a financial incentive to develop innovative solutions in order to enable its ramp up. The most important performance aspect of the fine line plating in this market space is plating uniformity or planarity. Plating uniformity, trace/via top planarity, which measures how flat the top of the traces and vias are a few major features. This is especially important in multilayer processing, as nonuniformity on a lower layer can be transferred to successive layers, disrupting the device design with catastrophic consequences such as short circuits. Additionally, a non-planar surface could also result in signal transmission loss by distortion of the connecting points, like vias and traces. Therefore, plating solutions that provide a uniform, planar profile without any special post treatment are quite desirable.
