Optical Module Production Technical Requirements



The optical module is without doubt one of the core elements of the optical fiber communication system and a very powerful a part of the optical communication gear. Its primary operate is to understand the conversion of optical and electrical indicators. With the event of the Web, the quantity of community knowledge will increase exponentially, and the development of Web knowledge facilities drives the expansion of the optical module market. As one of many fundamental elements of community building, optical modules are very important in your complete community building.

The packaging type of optical modules can also be consistently evolving, the quantity is altering in a smaller and smaller path, and the pace, energy consumption, distance, price, and different facets are additionally consistently transferring ahead. This text focuses on the important thing factors of optical module processing and manufacturing course of management, and easy methods to handle and management such merchandise from the design, technical, and high quality facets.

Particular necessities for optical module PCB processing

Optical module merchandise typically have the next traits in line with the processing traits. The construction incorporates combined stress (excessive frequency + FR-4 or excessive pace + FR-4), managed depth milling, high-precision impedance strains, small spacing between connecting pads, buried copper blocks or buried Particular options similar to ceramics, nice strains, lengthy and quick or graded board edge headers, numerous again drilled holes, exact alignment, precision bond pads, nickel palladium gold, and so on.

Key High quality Requirements for Optical Module Merchandise

1. The corrosion resistance of the plug

The industry-accepted customary is that the plug and bond space have to go the porosity, salt spray take a look at, nitric acid fuel take a look at, and combined fuel (high-end product requirement) take a look at.

2. Plug floor high quality necessities

As a result of the sign is transmitted on the floor, it’s not allowed to reveal copper, nickel, palladium, or black spots; floor scratches, uneven defects, copper bumps & copper particles, pinholes, and nicks will not be allowed; the floor roughness have to be throughout the management vary.

3. Dimensional tolerance necessities

Plug size and width tolerance management: ±0.1mm; plug middle to board edge tolerance management: ±0.05 mm; plug distance tolerance management: ±0.05 mm; card slot diameter tolerance management: ±0.05 mm; card slot to plug middle tolerance management: ±0.1 mm.

4. Bonding efficiency necessities

Bonding pad dimension: ≥75 μm; bonding energy of 20 μm width gold wire ≥4 g; bleed potential management.

Key Course of Management of Optical Module Merchandise

Picture supply:

1. Plug floor dent management

  • There must be no scratches, pits, scratches, residual glue, and different defects on the floor of the laminated metal plate.
  • Use a sticky fabric to pre-clean the fused board floor earlier than arranging the board.
  • Use 35 μm copper foil because the isolation movie to rearrange the board (the graceful floor have to be clear).
  • Insert the clapboard when eradicating the board.
  • Utilizing X-ray drilling + automated chopping and grinding line manufacturing.
  • The vacuum diploma have to be managed within the drilling to forestall any mud between the duvet plate or the plate and the plate.
  • Grinding therapy earlier than electroplating should make sure that there is no such thing as a scratching on the board floor.

2. Management of copper nodules on the plug floor

  • VCP electroplating + low present density manufacturing.
  • Tough grinding and nice grinding floor therapy have to be carried out after electroplating.
  • It’s produced through the use of a ceramic brush curler grinding line.

3. Brush mark defect management on the plug floor

  • Pre-processing of graphic switch: Extremely-roughening therapy doesn’t permit mechanical grinding.
  • Pre-treatment of printed resist plating oil: pumice powder therapy can’t be mechanically brushed.
  • Secondary dry movie pre-treatment: sandblasting, no grinding.

Because the core system for photoelectric conversion in optical communication, optical modules are broadly utilized in knowledge facilities. Information facilities not solely require high-speed 40G, 100G optical modules and above but in addition require steady evolution in community structure to attain non-blocking community efficiency.

This text is a set of technical knowledge summed up by the creator based mostly on his personal expertise in making optical module PCBs and by consulting related supplies, hoping to be useful to the {industry}.
