Heterogeneous integration has become an important performance enabler as high-performance computing (HPC) demands continue to rise. The focus to enable heterogeneous integration scaling is to push interconnect density limit with increased bandwidth and improved power efficiency. Many different advanced packaging architectures have been deployed to increase I/O wire / area density for higher data bandwidth requirements, and to enable more effective die disaggregation. Embedded Multi-die Interconnect Bridge (EMIB) technology is an advanced, cost-effective approach to in-package high density interconnect of heterogeneous chips, providing high density I/O, and controlled electrical interconnect paths between multiple dice in a package. In emerging architectures, it is required to scale down the EMIB die bump pitch in order to further increase the die-to-die (D2D) communication bandwidth. Aa a result, bump pitch scaling poses significant challenges in the plated solder bump reflow process, e.g., bump height / coplanarity control, solder wicking control, and bump void control. It's crucial to ensure a high-quality solder bump reflow process to meet the final product reliability requirements. In this paper, a combined formic acid based fluxless and vacuum assisted reflow process is developed for fine pitch plated solder bumping application. A high-volume production (HVM) ready tool has been developed for this process.

Electronics manufacturers protect their circuit boards with conformal coatings. Conformal coatings serve as a barrier from environmental hazards and internal shorts, tin whiskers, and corrosion at the board level. Within conformal coatings different material chemistries specialize in shielding from an array of hazards and can be applied by multiple methods. The most common method is atomized spray which disperses the material into a fine mist. Alternatively, non-atomized coating controls the materials' dispense shape while maintaining the original liquid form. While some applications demand atomized spray and other scenarios overlap between atomized and non-atomized coating, this paper focuses on the circumstances where materials are ideally suited for non-atomized, selective coating.

Understanding The Crucial Role Of Dust Collectors In PCB Depaneling Machines Precision is paramount in PCB manufacturing, but it must go hand in hand with cleanliness. The intrusion of dust and debris can wreak havoc on delicate electronics. This article explores the pivotal role of dust collectors, their operation, and their necessity for various PCB depaneling machines. The Dust Collector's Crucial Function Dust collectors, also known as dust extractors, play an indispensable role in PCB manufacturing. When a PCB depaneling machine or a Laser PCB Depaneling machine is in operation, it generates a significant amount of dust. The dust collector promptly engages its vacuum motor to suction fine particles off the PCB, directing them to a collector equipped with a filtration system. Which Models Of PCB Depanelers Require Dust Collector? Several PCB depaneling machines necessitate dust collectors to ensure precision and cleanliness, including: I.C.T-5700 Offline Depaneling Machine, high precision, easy manual operation, dual platform, high efficiency. I.C.T-IR350 In-line depaneling machine, high precision, rapid operation, suitable for integration into the SMT production line for Industry 4.0 and AI automated production. I.C.T-LCO350 Laser cutting ensures cutting accuracy of 0.002, ideal for precise cutting requirements. I.C.T-100A Desktop PCB depaneling machine with compact size and high precision, suitable for smaller-scale operations. The Science Behind PCB Dust Collectors To prevent charged dust particles from adhering to PCBs, PCB depaneling machines are equipped with ionizing guns. These devices emit ions that neutralize static charges, making dust particles less likely to stick to freshly cut PCBs. The Vacuum Effect: Suctioning Away Dust During PCB depaneling, a cloud of dust is produced. The dust collector utilizes a robust suction system, often powered by vacuum motors, to draw dust away from the work area. Collected dust is transported to a designated collection point within the dust collector. A Difference In Design: I.C.T-5700 Vs. I.C.T-IR350 The placement of the dust collection apparatus distinguishes PCB depaneling machines. I.C.T-5700 has a bottom-mounted system capturing falling dust, while I.C.T-IR350 features a top-mounted system preventing dust settling on the work surface. This strategic difference ensures efficient removal of dust and debris, guaranteeing a clean and precise manufacturing process. Check: If you want to learn about the comparison of I.C.T-5700 and I.C.T-IR350. The Importance Of Filter Replacement The efficiency of a dust collector relies on its filter, necessitating periodic replacement every 1-3 years, depending on usage frequency. Regular filter maintenance ensures optimal performance. Dust Collectors: Keep Your PCB Manufacturing Clean And Precise Precision in PCB manufacturing is not solely about cutting-edge machinery but also about cleanliness. If you seek a dust collector for your PCB depaneling machine, contact us today to explore your options. Ensure your operations maintain cleanliness, efficiency, and meet the high standards of modern PCB manufacturing. Don't let dust compromise your precision – let's keep it clean together!

Fine pitch SMT devices, although certainly not new, present more of an assembly processing challenge than 50 mil pitch devices. In fact it seems that the finer the pitch the more difficult or narrower the process window becomes. Besides the pitch of the leads being less on fine pitch devices narrower pad width on the board is typical. With fine pitch designs the board fabrication process is also stressed in that the strip of mask between the pads is designed narrower, the alignment of the mask to copper becomes more critical

With the rapid trend towards miniaturization in surface mount and MEMs lid-attach technology, it is becoming increasingly challenging to dispense solder paste in ultra-fine dot applications such as those involving chip capacitors or BGA packages, as well as dispensing ultra-fine lines in MEMs lid-attach applications. In order to achieve ultra-fine dots and fine line widths while dispensing solder paste, both the solder material and dispensing equipment need to be optimized. Optimizing the equipment can be very challenging, as there are many input variables that can affect the dispense quality of the solder paste. In this paper we will evaluate the many equipment variables involved in the solder paste dispensing process, and the impact these variables have on the dispense quality of the solder paste.
