Electronic Manufacturing Services (EMS) and tiers

Electrical Wholesalers

EMS that is Electronic Engineering Manufacturing Service discusses the strategy of integrating manufactured goods development, prototyping and mechanisation services into a traditional EMS commerce, to connect impending interactions. A typical EMS contribution will fright the design phase, then continue to maintain the client in progress, prototyping, tooling and construction all the way to the testing phase, permitting for quicker ramp-up as the invention is equipped for mass-production up-front. This Electronic Manufacturing Service helps theElectrical Wholesalers in distribution and sale.

Electrical Wholesalers

The term EMS was first coined by ESCATEC and it is followed by numerous Tier 2 and Tier 3 manufacturers. Superior companies (Tier 1) have offered the full concept to mass-production and often taking a post in the scholarly possessions, becoming more parallel to original design manufacturers.


Electronics Manufacturing Services is a term used for companies that propose, fabricate, experiment, allocate, and deliver return/repair services to electronic components and gatherings for original manufacturers. This concept is termed as Electronics contrast Manufacturing.

Most of the electronics for the consumer are manufactured in China owing to the cost needed for maintenance, material availability, speed and so on. Shenzhen and Penang city are the major contributors to the production of EMS.


The EMS industry starts its duty in the late 1970s when Solectron was established.  It helped the large scale products to handle the in-house assembly. These new companies presented elasticity and relieving human resources concerns for smaller companies. They planned to do it in a large economy in production and raw materials pooling, expertise the design of the industries. It will create a warranty and added value service. It helps the retailers to get more number of products to satisfy the demand.

Next step is The development of Surface Mount Technology (SMT) on printed circuit boards (PCB) that allows the rapid assembly of electronics. EMS players like SCI and Avex wriggled to happen as OEMs would pull contract or change vendors constantly. In the early part of 2000 EMS plays aggressively in the market share.


The EMS industry is commonly divided into Tiers by their revenue:

Tier 1: >$5 Billion

Tier 2: $500M to $5B

Tier 3: $100M to $500M

Tier 4: <$100M

The distinction is drawn between EMS that concentrates in High Mix Low Volume (HMLV) and High Volume Low Mix (HVLM). It refers generally to the intricacy or different prototypes of the PCB assembly. Volume denotes to the number of units built, with products like consumer electronics on the high end and prototype, medical electronics or machinery on the low end.

During the hey-day in the 1990s, EMS players consistently taught properties in high-cost localities. they largely focused on printed circuit board fabrication, parting system gathering to the original. EMS companies largely disparaged industries outside the world of information processing and communications.

In recent times, EMS players have shifted production to low-cost geographies; embraced non-traditional industries including consumer electronics, medical and instrumentation; and added substantial vertical competencies, stretching from design and ODM through system assembly, test, delivery and logistics, warranty and repair, network services, software and silicon design, and customer service.
