Manufacturing Services

  •      Electronics Manufacturing Services

The main objective of EMS is to create repeatable, high quality, complaint electronics parts at the least cost possible. Today most new designs are manufactured using SMD technology. There are two parts of electronics manufacturing.

  • 1) PCB Fabrication
  • 2) Assembly
  •  

Prototyped and tested PCB gerber’s are sent to PCB FAB houses or turnkey houses (Who does FAB and ASSEMBLY often at a higher cost). The Fist step in manufacturing is fabrication of PCBs. Even after a spin of prototypes, it isn’t advisable to straight away move to produce large number of boards. This needs to be taken in stages such as pre-production, beta1 build, beta2 build, P1 etc. with each stage undergoing a thorough set of analysis including the yield, durability, robustness and other quality factors needed for the design. Each stage of production is usually a batch of production with incremental quantity.

Fabricated boards are inspected and checked for defects. All good boards are sent to PCB assembly hours together with all components, stencil etc. The Assembly house builds manufacturing and test jigs as required. They usually load components in SMD pick and place machines and carry out assembly of board as panel or batches. After assembly PCBA is tested again for assembly defects such as solder bridge, dry or no solder etc and are approved, corrected or discarded. Approved and corrected boards are then tested and programmed as desired by the assembly house(if desired and often at a cost).

 

     Plastic Part Manufacturing Services

The main objective of EMS is to create repeatable, high quality, plastics parts at the least cost possible. Almost all plastic parts are manufactured using injection moulding technique. The most important part of injection moulding is a mould which is usually a stainless-steel jig which helps inject molten plastic forming the desired plastic part needed. The draw back of this process is that a mould is very costly and needs to be made for every design or every batch of design of plastic parts.

Often designers use other manufacturing processes such as FDM or SLA 3D printing or 3D CNC subtractive manufacturing to create and functionally test enclosures and other plastic parts. Tested and approved parts are sent to mould makers, who then prepare moulds and iterates on it to create desired parts as needed. Once consistent parts are received the moulds are sent to injection lines for serial production.
