Control of Counterfeit Parts in Electronic Manufacturing Services

SMT.jpg

In recent times, the Electronic manufacturing segment has been seized of the problem of counterfeit parts and the subject of ‘Control of Counterfeit Parts’ is gaining huge momentum.

Many of the suppliers have very poor parts control and internal corruption is rampant. Even some of the defence and aerospace assemblies have seen counterfeits showing up. This problem also has a direct relation to customers declaring “I wanted it yesterday” & “Lowest price” slogans.

Buying from manufacturers directly or from their authorized distributors should become a practice with EMS providers. Training the entire supply chain not only internally, but also our sub suppliers on CCP will see a marked improvement.

Customers giving realistic forecasts well in advance will help electronic manufacturing companies source their components only from ‘Authorized Distributors or Resellers’ coupled with ‘Mandatory COC’ will mitigate to a large extent the problem of Counterfeit parts and control more effective.

We should have stronger business regulations, tighter counterfeit laws and more reliable shippers. Electronic and business confederations viz. ELCINA, CII, FICCI should pitch in with more number of seminars and awareness programs to highlight the effect of counterfeit parts and train the industry in effectively mitigating them.

Solder Paste Inspection (SPI)

In any Electronic Assembly one of the prime reasons for post SMD assembly failures is perhaps Dry Solder / No Solder. Avoidance of these would result in higher yield (lower rejection PPM) thereby increasing productivity & profitability

In an SMT line, in-line SPI with 3D viewing facility will augment your process perfection in combination with the Automatic Optical Inspection which will facilitate detection and elimination of soldering failures. We will be able to measure volume, height, thickness, paste bridging etc. and compare with the prescribed values for a particular assembly. This will completely avoid replacement of components post solder due to dry or no solder thereby eliminating extra production costs. Other benefits are Process control through feed back to paste printer and control of stencil cleaning cycle.

We at SGS Tekniks have implemented 3D In-Line Solder Paste Inspection in our SMT line at our Manesar plant to perfect the process of soldering.
