   Item 1.  Security and Issuer.

     The class of equity securities to which this statement relates is the
common stock, $0.001 par value per share (the "Common Stock") of Manufacturers'
Services Limited, a Delaware corporation ("MSL"). The principal executive
offices of MSL are located at 300 Baker Avenue, Suite 106, Concord, MA 01742.

     This Schedule 13D is being filed due to the acquisition (the
"Acquisition") on March 14, 2002 (as described below in Item 3) of 300,000
shares of 5.25% Series A Convertible Preferred Stock, $.001 par value per
share, (the "Preferred Stock") of MSL and warrants to purchase up to an
aggregate of 582,751 shares (the "Warrants") of Common Stock of MSL.

     The Preferred Stock has a stated value of $50.00 per share and is
convertible into Common Stock at an initial conversion price of $6.44 per share
at any time prior to the scheduled redemption date of March 14, 2007 at the
option of the holder of the Preferred Stock. MSL may convert some or all of the
Preferred Stock into Common Stock prior to its scheduled redemption date of
March 14, 2007 if the closing price of the Common Stock exceeds 150% of the
conversion price for the Preferred Stock for at least 15 of 20 consecutive
trading days. If MSL effects a conversion of the Preferred Stock prior to
September 14, 2003, it will make a payment to the holders of Preferred Stock
equal to six quarterly dividends on the Preferred Stock, less any dividends
previously paid. Each holder of Preferred Stock is entitled to vote on all
matters submitted for a vote to the holders of the Common Stock and is entitled
to that number of votes equal to the number of shares of Common Stock into
which such holder's Preferred Stock could be converted. Each share of Preferred
Stock pays dividends at a rate of 5.25% per annum on its liquidation value.
Such dividends are payable quarterly on March 31, June 30, September 30 and
December 31 of each year to the record holders of Preferred Stock at the close
of business on the date that is 10 business days prior to the applicable
dividend payment date. MSL has the option to pay these dividends in cash or in
shares of Common Stock, which shares of Common Stock will be valued for such
purpose at 95% of their market value. A copy of the Certificate of Designations
for the Preferred Stock is attached hereto as Exhibit 1 and is incorporated
herein by reference.

     The Warrants are exercisable until March 14, 2007 at an initial exercise
price of $7.02 per share of Common Stock. In general, after March, 14, 2003,
MSL may force the exercise of the Warrants if the closing price of the Common
Stock exceeds 175% of the exercise price for the Warrants for at least 15 of 20
consecutive trading days. A copy of the Form of Warrant is attached hereto as
Exhibit 2 and is incorporated herein by reference.
