A component mounter provided with head, a device for moving head, transfer unit, and a mounting controller. Round plate is an example of a container for paste. The mounting controller, in the first operation mode, images components held by multiple nozzles using an imaging device before transfer is performed, and recognizes the position and/or orientation of each component based on the image of each component. Further, the head and the head moving device are controlled based on the position and/or orientation of each component such that a coating layer is transferred to connection terminals of each component at a transfer area of each of the components set in advance that does not include a margin based on the holding deviation of each component.

A method for connecting an electronic component to a circuit board is disclosed. Initially, a substrate and an electronic component having solder located between them are placed under a flashlamp. Multiple light pulses from the flashlamp are applied to the electronic component, substrate and solder until the solder reflows. During the application of the light pulses, the power of one of the light pulses from the flashlamp and the temperature of the electronic component are measured, the measured power is converted to radiant exposure, and in response to the measured temperature of the electronic component, the duty cycle of a next light pulse is adjusted adaptively according to the radiant exposure of the one light pulse.

The present disclosure provides an apparatus for determining mounting information. The apparatus according to the present disclosure may be configured to acquire solder measurement information indicating a state of a solder printed on a first substrate, determine whether or not the state of the solder is changed from states of solders printed on second substrates, which are measured prior to measurement of the first substrate, based on the solder measurement information, upon the determination that the state of the solder is not changed, determine mounting information indicating a mounting condition for mounting a first component on the first substrate using one or more models, and deliver the mounting information to a mounter. The one or more models may be configured to output the mounting information based on a correlation between states of a second component before and after a reflow process for each of the second substrates.

A correction amount calculation device includes a first acquisition section and a correction amount calculation section. The first acquisition section is configured to acquire a first positional deviation amount, which is a positional deviation amount of a printing position detected by a printing inspection machine with respect to a pad position, and a second positional deviation amount, which is a positional deviation amount of a mounting position detected by a appearance inspection machine with respect to the pad position. The correction amount calculation section is configured to, based on the first positional deviation amount and the second positional deviation amount, calculate a correction amount, which is used in the mounting process of a board product to be produced later, regarding a third positional deviation amount, which is a positional deviation amount of the mounting position with respect to the printing position.

Disclosed is a warpage suppressing reflow oven, which comprises a reflow oven body, where a perforated steel plate circulating device comprising a perforated steel plate is disposed at a reflow-oven inner oven. A plurality of downdraft modules is arranged in the perforated steel plate, and the downdraft acting forces thereof face the upper panel. More than one air extractor is communicated with the plurality of downdraft modules via a plurality of pipelines. Under actuation of the air extractors, the downdraft modules generate downdraft acting forces to the bottom surfaces of the products, so that the products are flatly attached to the universal perforated carriers without warpage in a heat soldering process. Thereby, more uniform heating of the products and better contact of solder joints and effectively improving the yield of reflow soldering operations are achieved.
