AMS-WThe most economic and flexible MAP molding systemThe AMS-W is the most economic and flexible MAP molding system, dedicated to the latest trend in single sided packaging. It is the molding solution for products like QFN, BGA, BOC and BGA-MAP, including high end applications such as flip chip, multi chip array and stacked die.

Cost of ownership savingsThe cost price of your product is determined by a number of variables. Not only the cost of the materials used, but also the machine costs are calculated in order to obtain the cost of ownership for a product. The AMS-W molding system has an extremely low cost of ownership, compared to what is in the market. With the design of the AMS-W, the Fico engineers were challenged to achieve up to 40% lower cost of ownership when molding single sided packages. And as you can read further; they succeeded.

User friendlyA f lat touch screen provides a comfortable and intuitive user interface for operators and maintenance engineers. To allow fast creation of product recipes and reports, a virtual keyboard pops-up whenever user interaction is required.

Topedge moldingA unique feature of the AMS-W is the topedge construction. It makes the use of

...no siderail flash...

Revolution by designFor the design of the AMS-W Fico took a different approach. The machine not only

had to look good, it also had to be e r g o n o m i c a l l y accessable. Based upon 50 years of

experience in the semiconductor industry, combined with many customer reviews, a complete new design was created. All operator intervention is designed at the front of the machine, at comfortable heights.Together with an intuitive Man Machine Interface (MMI) the AMS-W is a revolution by design!

• One of the proposals of the AMS-W design team.

a gold layer redundant and prevents any flash on the siderail. The topedge strip covers the side of the board and guides the compound through the topedge strip over the board to the gate of the package.

Topedge molding is a proven technology, patented by Fico. It allows a large process window and since the gold layer is not necessary anymore for degating, there is a significant cost reduction in materials.

More informationCurious of what the AMS-W can mean for you? A demo on a running system? Please contact the Fico sales department for more information. We will be glad to help you with a dedicated cost of ownership calculation, answer your questions and work out an optimal proposal.

Cost reductionEpoxy determines the largest element of the price when calculating the cost of ownership of a product. Therefore this is where Fico achieved a significant cost reduction. Due to the topedge gating technology used in the AMS-W molding system, compound reductions of up to 25% are obtained. Injection channels are smaller and cull strength is no longer necessary for the degating process. A thinner cull means less waste.But not only the use of epoxy is reduced. Also the depreciation and labor costs for the AMS-W are reduced by up to 33%. Together with these factors, the AMS-W molding system offers you the best value for money.In addition as a tradition of Fico equipment, the fast conversions and high reliability contribute to a high utilization of the system.

Dynamic Temperature Control (DTC)

An AMS-W mold is divided into different temperature zones. This Dynamic Temperature Control (DTC), heats up the cull area to a higher temperature. The cull area needs more heat to melt off the pellet and to cure the waste (the cull). Since only the waste is heated up to a higher temperature, the cure time is drastically reduced, without influencing the temperature in the package. With the DTC-molding technology, the machine output can be increased up to 50%.

Anti warpageAfter the molding process, the boards are pushed on the anti-warpage table and are then immediately clamped and cooled down. The boards are cooled down in a controlled way so that they remain perfectly flat, in the correct shape.

• On the left a warped board, on the right a perfectly flat board from the AMS-W.

Short machine cycle timeAs a result of the small footprint the distance a leadframe has to cover is very

short. The AMS-W has 40% less moving parts, with 30% less handling time. Inside the press, the compound handler takes care of degating, cull removal and pellet

loading. All in one go, resulting in a mold open time of only 12 seconds.

High outputThe AMS-W is capable of handling leadframes or boards with dimensions of up to 75 x 280mm. An increase of 46% compared to the averagely used leadframe dimensions. Together with a 50% improved cycle time, the UPH of the AMS-W has more than doubled compared to what is currently common in the molding market. The AMS-W can process up to 400 leadframes per hour.

...the UPH of the AMS-W has more than doubled...

Low investment costsThe AMS-W is the most economic molding system available. Because of its attractive initial investment costs, it has a very high value for money. The small footprint of the AMS-W saves your valuable floorspace. A reduction of 50% is achievable.Since the AMS-W has only few product related parts, investment in these parts is reduced by 70%.

Interactive help systemAll machine manuals are available on the user interface. You can stay at the machine for the necessary information. The help system contains all operator and maintenance information necessary to keep the AMS-W up and running. Context sensitive help directly helps the user to solve alarms.

Easy maintenanceIn the AMS-W most parts are maintenance free. Easy access to the system components reduces preventive maintenance time.

Innovative solutionsIndependent from the outer dimensions of the machine, it contains 1, 2 or 3 presses. A one or two press ASM-W is field upgradable until all three press positions are taken. The presses of the AMS-W have a clamp force of up to 40 tons.

On the AMS-W nine new patents are pending. New innovations like a low friction plunger, topedge molding and in cycle mold cleaning are combined with eight already granted Fico patents.

Designed for flexibilityA product change over on the AMS-W can be carried out very easily. The mold parts can be exchanged within 5 minutes. If you change to a different package height, only the top plate needs to be exchanged.

The universal design of the AMS-W results in few product related parts making the machine very flexible.

• The light blue line in the left graph shows the curing rate of the cull when the zone is not heated up to the higher temperature.

Time to marketAdvanced production techniques allow short production times. And since less product related parts are needed, the time to market is reduced significantly.

Air cushion transportAll boards are slided through the machine. Therfore very thin boards can be handled. Unmolded boards are lifted with air so that they can easily be transported wihout any force on the board. This unique air cushion transport also allows transport of BOC boards where the wires stick through the underside of the board.

Board and cavity vacuumBoard vacuum is used to fix the board on the mold. It prevents shifting of the board due to the movement of the clamp. It also prevents board lift and wires touching the top cavity. Heating of the board will be more uniform.

Cavity vacuum makes the flow of the compound easier. It reduces the chance of air entrapment in the cavity and makes sure that the package is completely filled. The cavity vacuum level can even be controlled depending on the transfer position. Therefore it is especially suitable for flip chip molding, stacked die, multi array or any other complex package.

Press designThe unique press design enables a mold open time of only 12 seconds. This is the shortest mold open time in the market.

A unique patented floating clamping system gives many advantages over an electro mechanical system:

• compactpressdesign• equalclampingontheboard• very low force for unwanted object

detection to prevent damage

Cassette handlerThe cassette handler positions the cassette so that a leadframe can be pushed in or out of the cassette. The machine is equipped with a loading and an offloading deck, allowing slot to slot copy. The optional four deck version uses different front-end and back-end cassettes for unmolded and molded leadframes.

A vision system checks the orientation of the leadframe. Even without identification holes it is possible to check the orientation of a board by looking for the gold marks on top of it, using the optional top light.
