Reducing Glue Residue and Improving Hole Shape in Rogers RO3003 PTFE Laser Drilling

With breakthroughs in 5G technology, the realization of automotive autonomous driving is becoming increasingly imminent. The autonomous driving process requires the installation of numerous sensors to detect the surrounding environment, with 77G millimeter-wave radars being widely used for vehicle body perimeter detection (Figure 1). To reduce signal transmission loss in automotive radar PCB products, radar antenna surfaces predominantly use PTFE-based high-frequency PCB materials.

Abstract
In order to reduce signal loss, automotive millimeter-wave radar boards use PTFE highfrequency materials as the base material on the radar antenna surface. The commonly used PTFE material inthe industry is RO3003 supplied by Rogers Corporation, which uses molten PTFE as the resin base, and thefller inside is SiO, with a diameter ranging from 5-70 um. Because PTFE resin itself has a high melting poinand is dificult to decompose, at the same time, this material has a high proportion of SiO, fller and a largeparticle size. Laser blind hole processing has always been a problem in the industry. If the energy is large, itis easy to carbonize and agglomerate, resulting in molten black spots. Attached to the wall and bottom of thehole, the energy is small, the hole shape is very irregular, In this paper, the research on the selection of laserparameters of the laser light source and the optimization of the bottom glue removal method have effectivelreduced the residual glue, and the hole shape has also been greatly optimized. This greatly improves productreliability and processability.

Rogers PCB Board Material: RF Builds
BS Interconn's Rogers PCB board material is dedicated to high-frequency boards that are designed to minimise signal loss, particularly in millimetre-wave automotive radar systems. Focuses on Rogers's RO3003 PTFE, which is based on a molten PTFE resin and has SiO₂ filler, and is therefore recommended for use in antenna-side circuitry where stable RF performance is critical. It further states that We also provide Rogers PCB material in We's RF circuit board line.
What the Process Covers
It explains the main steps employed in the processing of Rogers PCB material: stack-up design, etching opening, laser drilling, desmear, PTH, panel plating and pattern etching.
That's important because RO3003 is not a very easy-to-process medication. The article goes on to explain that if the laser energy is not correct, there may be a residue or blackening in the hole, and the process control has a direct effect on the quality and reliability of the hole.
Better Hole Quality for RF Builds
The site is a comparison of IR, CO2 and UV laser drilling results. The practical aspect of its main point is that, if the energy is well adjusted, the CO2 laser may be able to improve the shape of the holes and eliminate the residue, while the UV laser, if it is adjusted correctly, can provide a clean bottom to the blind holes with a minimum number of black spots. This level of control enhances bonding and helps create a more reliable service board.

| The upper and lower aperture ratio is (40-60)%. Increasing the energy results in more severe blackening, with the risk of burn-through as the center bottom copper becomes brighter. |
The upper and lower aperture ratio is (75-85)%, with no loss in the center and a bright appearance, and fewer black spots. |
The upper and lower aperture ratio is (85-95)%, with no black spots, slight bright layering in the center, and copper loss at the bottom of 1-2μm. The filler on the hole wall is prominent. The efficiency is relatively low, approximately 1/8 of that of CO2 equipment for the same number of holes. |

in conclusion
Using CO laser drilling, a smaller energy setting can achieve a better hole shape with less residue at the bottom. Based on this, further processing with UV can result in a cleaner blind hole bottom, ensuring effective bonding at the bottom of the blind hole.
