Top 5 Test & Burn-In Socket Suppliers for 2018


    April 25, 2019: VLSIresearch releases latest report detailing the 2018 top five suppliers of test and burn-in sockets to the semiconductor industry. 


    The top five suppliersYamaichi Electronics, Cohu, Enplas, ISC, and LEENOaccounted for 42% of the total market in 2018, up from 39% the previous year.  Yamaichi Electronics kept the top position with sales of $124M closely followed by Cohu who climbed to second place following their acquisition of Xcerra. Enplas, a specialist supplier of burn-in sockets, posted revenues of $104M which is around $18M ahead of fourth place ISC. LEENO took the fifth spot with revenues of $76M.


    After the exceptional growth in the test and burn-in socket market in 2017, 2018 was a year of digestion with market growth of only 2.3%.  Yamaichi Electronics, Enplas, and ISC all posted strong revenues similar to their 2017 highs. However, LEENO outgrew the market with sales 9% higher than the previous year. 2018 was also another year of consolidation for the industry. The top 5 suppliers continued to increase their dominance, driven primarily by Cohu’s acquisition of Xcerra.


    John West, Managing Director, VLSIresearch Europe commented: “The rollout of 5G over the next few years is going to present multiple technical and cost challenges for suppliers of test and burn-in sockets. This may favor the larger suppliers with the resources to overcome these problems, but I wouldn’t rule out the possibility of some smaller companies playing a major role”.
